Question

If PQRS is a parallelogram, find angle p - angle r

Answer 1

We know that a parallelogram have opposite angles equal.

Means,

angle p = angle r

and,

angle q = angle s

So, if angle p = angle r

then, angle p - angle r = 0

Answer 2

Answer:

We know that the opposite angles of a parallelogram are equal .

So angle p - angle r = zero
