Question

Practice set 5.1
1. Diagonals of a parallelogram WXYZ intersect each other at point 0. If ZXYZ = 135°
then what is the measure of ZXWZ and ZYZW ?
If I(OY)= 5 cm then /(WY)= ?​

Answer 1

Step-by-step explanation:

In a parallelogram , opposite angel are congruent

xyz =xwz =135°

also ,wx ||zy

so ,yzw +xwz =180°

yzw + 135° = 180 °

yzw = 180- 135°

yzw =45°

now l(oy) =5

we now that diagonal of a

parallelogram bisect each other.

so ,l(WY) = 2 × oy = 2×5 = 10cm.

Answer 2

Answer:

in paralleolgram opposite sides are equal...
