Has one pair of parallel and unequal opposite sides (bases); AD II BCHas one pair of congruent non-parallel sides (legs); AB ≅ CDLower base angles are congruent; ∠B ≅ ∠CUpper base angles are congruent; ∠A ≅ ∠DThe isosceles trapezoid theorem states that if a quadrilateral with one pair of parallel sides is an isosceles trapezoid, its legs must be congruent.
