This resource is designed to introduce students to the types of quadrilaterals and their properties. The notes begin with a "family tree" which shows the relationship between the quadrilaterals: parallelogram, rectangle, square, rhombus and trapezoid. Students will then apply the properties to find missing angles and sides of various quadrilaterals. Note: Two questions involve students writing an algebraic equation to solve to find missing angles. There is a corresponding homework assignment included!
