The document discusses the characteristics of trapezoids and kites. It defines trapezoids as quadrilaterals with at least one pair of parallel sides and defines isosceles trapezoids as trapezoids with congruent legs. The document also discusses properties of trapezoids such as their diagonals potentially being congruent or noncongruent and describes how to find the median of a trapezoid.
