8.6Trapezoids and Kites
Quick Answer
A trapezoid has exactly one pair of parallel sides (bases). An isosceles trapezoid has congruent legs, congruent base angles, and congruent diagonals. A kite has two pairs of consecutive congruent sides; its diagonals are perpendicular.
Essential Question
How do the properties of isosceles trapezoids and kites each arise from their definitions, and how do they differ from parallelogram properties?
Learning Goals

- 2Apply isosceles trapezoid properties.
- 3Apply kite diagonal properties.
- 4Find missing angles and lengths in trapezoids and kites.
