Question

Y W P 8 cm E R WERP is a square. Find.

1. m2WER=
2. measure of PE =_______
3. measure of WA =
4. Value of y=​

Answer 1

The answer should honestly be B

Answer 2

1) All interior angles of a square are right angles, so angle WER measures 90°

2) All squares are parallelograms, and diagonals of a parallelogram bisect each other, meaning PA=AE=8 cm. Thus, PE=16 cm

3) All squares are rectangles, and diagonals of a rectangle are congruent, meaning WR=16 cm. Then, using the fact that the diagonals bisect each other, we get that WA=8 cm

4) If we consider right triangle WPR, we know it is isoceles because all sides of a square are congruent. So, the length of WP is:

`(16)/( √(2) ) = 8 √(2)`
