Question

The four angles of a quadrilateral are equal.find thier measure

Answer 1

let the angles of quadrilateral be x
total sum of all angles of quadrilateral is 360
therefore
x+x+x+x= 360
4x=360
x=90
sum of each angle is 90

Answer 2

let the angles be x.

4x=360

x=360/4

=90

The measure of the sides are 90.
