Share. - 10644521 The median of a trapezoid is a segment parallel to the bases that connects the midpoints of the non-parallel sides. The base angles (angles formed between non-parallel sides and parallel sides) are equal in an isosceles trapezoid. Exclusive Definition of Trapezoid. Isosceles trapezoid — a trapezoid with one pair of base angles and the non-parallel pair of sides equal in measure. where h is the height and b 1 and b 2 are the base lengths. Cite. Tessellation – a covering or tiling of a plane with a pattern of figures so there are no overlaps or gaps. Consequently, the legs will be congruent to each other as well.
