An isosceles trapezoid is a special trapezoid with congruent legs and base angles. Isosceles trapezoids have some additional properties: Base angles of a trapezoid are congruent. Isosceles trapezoids still have all the properties of trapezoids, so it still has one pair of parallel sides. An isosceles trapezoid (called an isosceles trapezium by the British; Bronshtein and Semendyayev 1997, p. 174) is trapezoid in which the base angles are equal and therefore the left and right side lengths are also equal..

Characterizations of Trapezoids Martin Josefsson Abstract. There are several theorems we can use to help us prove that a trapezoid is isosceles. In Euclidean geometry , the convention is to state the definition of an isosceles trapezoid without the condition that the legs are congruent, as this fact can be proven in Euclidean geometry from the other requirements. One aim for this paper is to show that many of the known properties of trapezoids are in fact characteriza-tions. The two parallel sides are called the trapezoid's bases, and the two non-parallel sides are referred to as the legs. In an isosceles trapezoid the straight line which passes through the diagonals intersection parallel to the bases bisects the angle between the diagonals.
