What is the definition of an isosceles trapezoid?

Back

An isosceles trapezoid is a trapezoid in which the non-parallel sides are equal in length.

Front

How do you determine if two triangles are congruent?

Back

You can determine if two triangles are congruent by comparing their sides and angles using postulates like SSS, SAS, ASA, AAS, or HL.
