Let's look at these trapezoids now. Segment AB is adjacent and congruent to segment BC. Thus, if we define the measures of? Adds another specification: the legs of the trapezoid have to be congruent. Next, we can say that segments DE and DG are congruent. R. to determine the value of y.
Subtracting 2(72°) from 360° gives the sum of the two top angles, and dividing the resulting 216° by 2 yields the measurement of x, which is 108°. Example Question #11: Trapezoids.

Let's begin our study by learning. Thus, we know that if, then.
Isosceles Trapezoids. Its sides and angles. Trapezoid is an isosceles trapezoid with angle. Try Numerade free for 7 days. Because segment TR is the other base of trapezoid TRAP, we know that the angles at points T and R must be congruent.
