Unique feature of a trapezoid

Back

Trapezoids have only one pair of parallel sides, unlike parallelograms which have two pairs.

Features of an isosceles trapezoid

Back

Isosceles trapezoids have congruent legs, congruent lower and upper base angles, congruent diagonals, and supplementary opposite angles.

Properties of a kite

Back

Kites have two pairs of consecutive congruent sides, but opposite sides are not congruent. They have perpendicular diagonals, one pair of congruent angles, and one pair of bisected angles.
