Understanding Trapezoids and Kites: Properties and Definitions

This lesson explores trapezoids and kites, focusing on the unique characteristics of isosceles trapezoids. Learn about the definition of a trapezoid, identifying its parallel sides (bases) and non-parallel sides (legs). Discover the properties of isosceles trapezoids, including congruent base angles and congruent diagonals. We also explain the concept of the median of a trapezoid, which connects the midpoints of the legs, is parallel to the bases, and represents half the sum of the base measures.

  1. Trapezoids and Kites Lesson 6-5 Lesson 6-5: Trapezoid & Kites

  2. Trapezoid A quadrilateral with exactly one pair of parallel sides. Definition: The parallel sides are called bases and the non-parallel sides are called legs. Base Trapezoid Leg An Isosceles trapezoid is a trapezoid with congruent legs. Isosceles trapezoid Lesson 6-5: Trapezoid & Kites

  3. Properties of Isosceles Trapezoid 1. Both pairs of base angles of an isosceles trapezoid are congruent. 2. The diagonals of an isosceles trapezoid are congruent. B A Base Angles D C Lesson 6-5: Trapezoid & Kites

  4. Median of a Trapezoid The median of a trapezoid is the segment that joins the midpoints of the legs. The median of a trapezoid is parallel to the bases, and its measure is one-half the sum of the measures of the bases. Median Lesson 6-5: Trapezoid & Kites
