Question

Pqrs is a parallelogram and angle 1 and angle 2 are two exterior angle .show that (1 )angle 1 = angle 2. (2) angle 1= angle 2= angle 3= angle 4

Answer 1

1) angle 1 = angle 2.
because, angle 1 = angle 2 are adjacent angles.
2) if, angle 1 = angle 2 so, angle 1 = angle 3 and angle 2 = angle 4 because, these angles are opposite to each other.

Answer 2

Answer:

it is below

Step-by-step explanation:

1) angle 1 = angle 2.

because, angle 1 = angle 2 are adjacent angles.

2) if, angle 1 = angle 2 so, angle 1 = angle 3 and angle 2 = angle 4 because, these angles are opposite to each other.
