A quadrilateral with one pair of sides that are parallel and another pair of sides that are not parallel but have equal lengths; the base angles are equal in measurement.
A trapezoid with the un-parallel opposite sides congruent.
a trapezoid with the non-parallel sides congruent
a four-sided figure which has two opposite sides of the same length, and the shape is vertically symmetrical
a quadrilateral with one pair of parallel sides and congruent base angles, or it is a trapezoid with congruent base angles
a trapezoid in which the base angles are equal so
a trapezoid with the two non-parallel sides the same length
A trapezoid in which the two nonparallel sides are congruent.
A trapezoid with congruent legs.
A trapezoid whose two nonparallel sides are the same length (Lesson 6.3).
An isosceles trapezoid (isosceles trapezium in British English) is a quadrilateral with a line of symmetry bisecting one pair of opposite sides, making it automatically a trapezoid. Also, an isosceles trapezoid's base angles are congruent.
