  1. Trapezoids and Kites

  2. Trapezoids and Kites Atrapezoid is a quadrilateral with exactly one pair of parallel sides. The parallel sides are of trapezoid are called bases. The nonparallel sides are called legs. The two angles that share a base of a trapezoid are called base angles. A trapezoid has two pairs of base angles.

  3. Trapezoids and Kites An isosceles trapezoid is a trapezoid with legs that are congruent. ABCD below is an isosceles trapezoid. The angles of an isosceles trapezoid have some unique properties.

  6. Trapezoids and Kites Problem 1: CDEF is an isosceles trapezoid and m<C = 65. What are m<D, m<E, and m<F?

  7. Trapezoids and Kites Problem 1b: PQRS is an isosceles trapezoid and m<R = 106. What are m<P, m<Q, and m<S?

  8. Trapezoids and Kites Problem 2: The second ring of the paper fan consists of 20 congruent isosceles trapezoids that appear to form circles. What are the measures of the base angles of these trapezoids?

  9. Trapezoids and Kites Problem 3: Find the measures of the numbered angles in each isosceles trapezoid.

  10. Trapezoids and Kites Problem 3b: Find the measures of the numbered angles in each isosceles trapezoid.

  11. Trapezoids and Kites Problem 3c: Find the measures of the numbered angles in each isosceles trapezoid.

  12. Trapezoids and Kites In lesson 5.1 you learned about the midsegments of triangles…What are they???? Trapezoids also have midsegments. The midsegment of a trapezoid is the segment that joins the midpoints of its legs. The midsegment has two unique properties.
