The length of the mid-segment is equal to 1/2 the sum of the parallel bases, in a trapezium. Basic Terminology for Trapezium . The sum of two pairs of adjacent angles of a trapezium formed between the parallel sides and one of the non-parallel side is 180 degrees. The shortest distance between the parallel sides is 6cm so h = 6. trapezium definition: 1. a flat shape with four sides, where two of the sides are parallel 2. a flat shape with four….

One pair of non-parallel sides. And one pair of adjacent angles on the longer parallel side are acute. Question: What properties does a trapezium have? A trapezium doesn’t have rotational symmetry so the order of rotational symmetry is 1. The bases of the trapezium are parallel to each other (MN ⫽ OP). The diagonals of trapezium bisect each other. Adjacent angles are supplementary. None of the sides, angles, and diagonals are congruent. The set of parallelogram is a subset of trapezium .
