Geometry Unit Five Word Bank Diagonal A segment from one vertex to another vertex in a polygon. Isosceles Trapezoid A trapezoid with congruent legs. Median (of a trapezoid) A segment from the midpoint of one leg to the midpoint of the other leg in a trapezoid. Its length is the average of the lengths of the two bases of the trapezoid. Midsegment Another name for the median of a trapezoid.
