Introduction An Isosceles trapezoid, as shown above, has left and right sides of equal length that join to the base at equal angles.. Properties of trapezoids A trapezoid is isosceles if and only if its base angles are congruent. A trapezium has the following properties: (a) Opposite sides are parallel. 4.5: Properties of Trapezoids and Kites Objective: To recognize the properties of sides, angles, and diagonals of trapezoids. The adjacent sides of a trapezoid are congruent. It is a special case of a trapezoid.Alternatively, it can be defined as a trapezoid in which both legs and both base angles are of the same measure. Characterizations of Trapezoids Martin Josefsson Abstract. The perimeter of an isosceles trapezoid is … Let’s see if this will help us answer the question. Isosceles trapezoids still have all the properties of trapezoids, so it still has one pair of parallel sides. They also form congruent triangles. When a trapezoid has two sets of parallel sides, it is a more specific type of trapezoid called a parallelogram. The interior angle measure of an isosceles trapezoid will equal 360 degrees and the adjacent angles are supplementary. Explore: 1. The upper base angles are congruent.
