A trapezoid is a quadrilateral that has only one set of parallel sides. Diagram:
Properties: Only one set of parallel sides (bases). The non-parallel sides are called legs.
Diagram:
Properties: All the properties of a trapezoid Non-parallel sides are congruent. Diagonals are congruent. Base angles are congruent. Opposite angles are supplementary.
Word Problems:
1.) The bases of an isosceles trapezoid ABCD measure 10 cm and 20 cm. The height (altitude) is 12 cm. How long are the legs AB and CD?
2.) Given: Isosceles trapezoid ABCD with BC ||AD. If m<A = 4x+20 and m<D = 2x+38, find m<A, m<B, m<C, and m<D.
3.) In isosceles trapezoid KIME, <K and <E are the base angles. If IK = 11 and ME = 3x - 1, what is the value of x?
4.) In isosceles trapezoid ABCD, BC||AD. The measure of <ADC=4x+20 and the measure of <DAB = 8x - 20. Find the value of x, <ADC, <DAB, <BCD, and <ABC.
