If the base angles of a trapezoid are congruent, the diagonals are congruent.
<h3>Properties of a trapezium?</h3>
A trapezium is a quadrilateral and the sum of the interior angles is 360 degrees. Therefore, the properties of a trapezium includes the following:
- The bases are parallel by definition.
- Each lower base angle is supplementary to the upper base angle on the same side.
- If the base angles are congruent, therefore, the trapezium is an isosceles trapezium. This means the diagonals are also congruent.
