Question

if the angle of a quadrilateral are equal.prove that it is rectangle

Answer 1

let the angles of quadrilateral =X
sum angles of quadrilateral =360
A/q X +X +X + X =360
so,X =360÷4
X=90
so,all angle of quadrilateral is equal to 90.
hence it is rectangle because all angle is equal to 90

Answer 2

Step-by-step explanation:

As we know that sum of angles of quadrilateral is= 360
