Challenge students to figure out the ordered pairs of a point that is at a fractional distance from another indicated point. Also, ask them to find the missing coordinates of points on geometric figures.
In geometry, the mid-point theorem helps us to find the missing values of the sides of the triangles. It establishes a relation between the sides of a triangle and the line segment drawn from the midpoints of any two sides of the triangle. The midpoint theorem states that the line segment drawn from the midpoint of any two sides of the triangle is parallel to the third side and is half of the length of the third side of the triangle.
In this article, we will explore the concept of the midpoint theorem and its converse. We will learn the application of the theorem with the help of a few solved examples for a better understanding of the concept.
The midpoint theorem states that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side and equal to half of the length of the third side. This theorem is used in various places in real life, for example in the absence of a measuring instrument, we can use the midpoint theorem to cut a stick into half.
The midpoint theorem states that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side and equal to half of the third side. Consider an arbitrary triangle, ΔABC. Let D and E be the midpoints of AB and AC respectively. Suppose that you join D to E. The midpoint theorem says that DE will be parallel to BC and equal to exactly half of BC. Look at the image given below to understand the triangle midpoint theorem.
Now, let us state and prove the midpoint theorem. The straight line joining the midpoints of any two sides of the triangle is considered parallel and half of the length of the third side. Consider the triangle ABC, as shown in the figure below. Let E and D be the midpoints of the sides AC and AB respectively. Then the line DE is said to be parallel to the side BC, whereas the side DE is half of the side BC, i.e.
The midpoint theorem converse states that the line drawn through the midpoint of one side of a triangle that is parallel to another side will bisect the third side. Consider a triangle ABC, and let D be the midpoint of AB. A line through D parallel to BC meets AC at E, as shown below. Now suppose that E is not the midpoint of AC. Let F be the midpoint of AC. Join D to F, as shown below:
By the midpoint theorem, DF BC. But we also have DE BC. This cannot happen because through a given point (in this case, D), exactly one parallel can be drawn to a given line (in this case, BC). Thus, E must be the midpoint of AC. This completes our proof of the converse midpoint theorem.
In math, we also have a midpoint theorem formula which has its applications in coordinate geometry. It can also be known as the midpoint theorem of a line segment. It states that if we have a line segment whose endpoints coordinates are given as (x1, y1) and (x2, y2), then we can find the coordinates of the midpoint of the line segment by using the formula given below:
Solution: It is given that X and Y are the midpoints of AB and AC. By the midpoint theorem, XY BC. Now, consider ΔABD. The segment XE is parallel to the base BD, and X is the midpoint of AB. By the converse of the midpoint theorem, E must be the midpoint of AD. Thus, XY bisects AD.
Consider ΔACF. Since B is the midpoint of AC and BG CF, the converse of the midpoint theorem tells us that G is the midpoint of AF. Now, consider ΔAFD. We have shown that G is the midpoint of AF. Also, GE AD. Thus, the converse of the midpoint theorem tells us that E must be the midpoint of FD. Therefore, DE = EF.
First of all, we note that AECF is a parallelogram as ABCD is a parallelogram which means AB = CD and so AE = CF (as E and F are the mid-points), and thus, EC AF. Now, consider ΔBAY. Since E is the midpoint of AB, and EX AY, the converse of the midpoint theorem tells us that X is the midpoint of BY, which means that BX = XY. Similarly, we can prove that XY = YD. Thus, BX = XY = YD = BD/3. Hence proved.
The midpoint theorem states that in any triangle, the line joining the mid-points of any two sides of the triangle is parallel to and half of the length of the third side. It has many applications in math while calculating the sides of the triangle, finding the coordinates of the mid-points, etc.
To prove the midpoint theorem, we use the congruency rules. We construct a triangle outside the given triangle such that it touches the side of the triangle. And then we prove that it is congruent to any one part of the triangle. It helps us to prove the equality between sides by using CPCTC rules.
To prove the converse of the midpoint theorem, consider a triangle ABC, and let D be the midpoint of AB. A line through D parallel to BC meets AC at E. Now suppose that E is not the midpoint of AC. Let F be the midpoint of AC. Join D to F. By the midpoint theorem, DF BC. But we also have DE BC. This cannot happen because through a given point (in this case, D), exactly one parallel can be drawn to a given line (in this case, BC). Thus, E has to be the midpoint of AC. This is the proof of the converse of the midpoint theorem.
The midpoint theorem can be applied to any triangle. When a line is drawn between the midpoints of any two sides of the triangle, it is always parallel to and half of the length of the third side. This theorem is applicable in all types of triangles.
The midpoint theorem statement is that "A line drawn between the midpoints of any two sides of a triangle is parallel to and half of the third side of the triangle". It can be mathematically represented as,
The midpoint theorem is used to define the relationships between the sides of the triangle. It is useful to find the missing side lengths, to prove the congruency of four triangles formed by joining the mid-points of the triangle, to find coordinates, etc. All these are the applications of the mid-point theorem in math.
Note: A color stop is a point on the Gradient Annotator (for linear and radial) or on the object (for freeform) that controls the color of the gradient. You can change the color of the color stops to set a gradient
For the linear and radial gradient types, when you click the Gradient tool in the toolbar, Gradient Annotator appears in the object. Gradient Annotator is a slider that shows a starting point, an end point, a midpoint, and two color stops for the starting and end points.
You can use Gradient Annotator to modify the angle, location, and spread of a linear gradient; and the focal point, origin, and spread of a radial gradient. Once the gradient annotator appears in the object, you can either use the Gradient panel or Gradient Annotator to add new color stops, specify new colors for individual color stops, change opacity settings, and drag color stops to new locations.
In linear and radial gradient annotators, dragging the circular end (starting point) of the gradient slider repositions the origin of the gradient and dragging the arrow end (end point) increases or decreases the range of the gradient. If you place the pointer over the end point, a rotation cursor appears that you can use to change the angle of the gradient.
You can set the spread of a color stop in the points freeform gradient. Spread is the circular area around the color stop in which a gradient is to be applied. To set the spread of a color stop, select the color stop and do one of the following:
A perpendicular bisector of a line segment is a line segment perpendicular to and passing through the midpoint of (left figure). The perpendicular bisector of a line segment can be constructed using a compass by drawing circles centered at and with radius and connecting their two intersections. This line segment crosses at the midpoint of (middle figure). If the midpoint is known, then the perpendicular bisector can be constructed by drawing a small auxiliary circle around , then drawing an arc from each endpoint that crosses the line at the farthest intersection of the circle with the line (i.e., arcs with radii and respectively). Connecting the intersections of the arcs then gives the perpendicular bisector (right figure). Note that if the classical construction requirement that compasses be collapsible is dropped, then the auxiliary circle can be omitted and the rigid compass can be used to immediately draw the two arcs using any radius larger that half the length of . 2ff7e9595c
