An isosceles trapezoid is a trapezoid in which the base angles are equal so cd. The trapezoid is equivalent to the British definition of trapezium (Bronshtein and Semendyayev 1977, p.

The diagonals (not show here) are congruent. The angles on either side of the bases are the same size/measure (congruent).

Opposite sides of an isosceles trapezoid are the same length (congruent).
