Question

if all the angles of a parallelogram are equal. prove that it is a rectangle

Answer 1

Step-by-step explanation:

let the all angles be x.

x+x+x+x = 360°

4x = 360°

x = 90°

Hence all angles are equal to x and x is equal to 90°.

Hence Proved.

Answer 2

Step-by-step explanation:

Let all the angles be x

x+x+x+x = 360°

4x = 360°

x = 360° /4

x=90°

Hence all the angles are equal.

Each angle measure 90°
