Question

I DONT KNOW THID BECAUSE I SKIP 4 GRADE SO I NEED THIS INFORMATION FOR A EXAM ON MY ALGEBRA 

Answer 1

A trapezoid is a quadrilateral with two parallel sides. It does not have any requirement as to the size of the angles.

In an isosceles trapezoid two pairs of angles are congruent, they are the base angles.
