### 6-6 HOMEWORK TRAPEZOIDS AND KITES

Finally, we can set equal to the expression shown in? Now, we see that the sum of? A kite is a quadrilateral with two distinct pairs of adjacent sides that are congruent. These properties are listed below. Properties of Trapezoids and Kites Now that we’ve seen several types of quadrilaterals that are parallelograms , let’s learn about figures that do not have the properties of parallelograms. Let’s practice doing some problems that require the use of the properties of trapezoids and kites we’ve just learned about. The parallel sides of a trapezoid are called bases. An isosceles trapezoid is a trapezoid whose legs are congruent. We learned several triangle congruence theorems in the past that might be applicable in this situation if we can just find another side or angle that are congruent. The remaining sides of the trapezoid, which intersect at some point if extended, are called the legs of the trapezoid. Let’s practice doing some problems that require the use of the properties of trapezoids and kites we’ve just learned about. Therefore, that step will be absolutely necessary when we work on different exercises involving trapezoids. R to determine the value of y. Exercise 1 Find the value of x in the trapezoid below. R by variable xwe have This value means that the measure of? These two properties are illustrated in the diagram below.

## Properties of Trapezoids and Kites

This is our only pair of congruent angles because? Thus, we have two congruent triangles by the SAS Postulate. Recall that parallelograms also had pairs of congruent sides. Where else have learned about the diagonals being perpendicular? In this section, we will look at quadrilaterals whose opposite wnd may intersect at some point. L have different measures.

Let’s look at the illustration below to help us see what a kite looks like. The definition of an isosceles trapezoid adds another specification: Apply properties of trapezoids. Let’s use the formula we have been given for the midsegment to figure it out.

We learned several triangle congruence theorems in the past that might be applicable in this situation if we can just find another side or angle that are congruent. While the method above was an in-depth way to solve the exercise, we could have homeeork just used the property that opposite angles of isosceles trapezoids are supplementary. The x-coordinate is The two-column geometric proof for this exercise is shown below. Since a trapezoid must have exactly one pair of parallel sides, we will need to prove that one pair of opposite sides is parallel and that the other is not in our two-column geometric proofs.

The top and bottom sides of the trapezoid run parallel to each other, so they are the trapezoid’s bases. There are several theorems we can use to help us prove that a trapezoid is isosceles.

Before we dive right into our study of trapezoids, it will be necessary to learn the names of different parts of these quadrilaterals in order to be specific about its sides and angles. A quadrilateral with exactly one pair of parallel sides. In the figure, we have only been given the measure of one angle, so we must be able to deduce more information based on this one item.

Trapezoid QRST is not an isosceles trapezoid. DGFwe can use the reflexive property to say that it is congruent to trwpezoids. This segment’s length ane always equal to one-half the sum of the trapezoid’s bases, or Consider trapezoid ABCD shown below.

Recall that parallelograms were quadrilaterals whose opposite sides were parallel. To make this website work, we log user data and share it with processors. We think you have liked this presentation. Thus, if we define the measures of? Segments AD and CD are also adjacent and congruent.

The two types of quadrilaterals we will study are called trapezoids and kites. Notice that a right angle is formed at the intersection of the diagonals, which is at point N. Show that ABCD is a trapezoid and determine whether it is an isosceles trapezoid.
