Has one pair of parallel and unequal opposite sides (bases); AD II BCHas one pair of congruent non-parallel sides (legs); AB ≅ CDLower base angles are congruent; ∠B ≅ ∠CUpper base angles are congruent; ∠A ≅ ∠DThe isosceles trapezoid theorem states that if a quadrilateral with one pair of parallel sides is an isosceles trapezoid, its legs must be congruent.
In Euclidean geometry, an isosceles trapezoid (isosceles trapezium in British English) is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides. It is a special case of a trapezoid.
A trapezoid: has a pair of parallel sides. is an isosceles trapezoid when it has equal angles from a parallel side. is called a " trapezium " in the UK (see below) Play with a trapezoid: The parallel sides are the "bases". The other two sides are the "legs".
An isosceles trapezoid has exactly one line of symmetry. It can be found by drawing a line through the midpoints of the two bases of our isosceles trapezoid. Use this isosceles trapezoid calculator to explore all the various properties of these particular trapezoids.
