What is an isosceles trapezoid?
An isosceles trapezoid is a trapezoid that has two pairs of congruent base angles and congruent legs
What is the same side interior angles theorem
When two parallel lines are intersected by a transversal the same side interior angles are supplementary
What is the determining factor for a trapezoid to be considered isosceles?
The diagonals have to be congruent
