THEOREM: The median of a trapezoid is parallel to the bases and half the sum of the lengths of the bases. A isosceles trapezoid is a trapezoid with congruent base angles. Note: The definition of an isosceles triangle states that the triangle has two congruent " sides ".

ANSWER ▷ The measure of aL is 52 Theorem: Let ABC be an isosceles triangle with AB = AC. Let M denote the b) Angle ABC = Angle ACB (base angles are equal). c) Angle AMB = Angle AMC Isosceles Triangle Theorem states that if two sides By the Converse of Isosceles Triangle Theorem, Proof: The base angles are congruent because it is.
