Answer 1

Answer:

A parallelogram with all sides and all angles equal is a rectangle

Proof :-

let the angles be 4x ( 4 sides and equal angles x )

we know that sum of all angles in quadrilateral is 360°

so, 4x = 360°

x = $\frac{360°}{4}$

x = 90°

according to the theorem , if the one angle in quadrilateral is 90° then it's a rectangle
