This investigation is about discovering the relationships sides, angles, and the diagonals of the: square, rectangle, rhombus, parallelogram, kite, and isosceles trapezoid. Try to discover which lengths are congruent, parallel, perpendicular, or bisected. Discover which angles are congruent, complementary, supplementary, or bisected. Try to generalize your findings by using descriptions like opposite or consecutive with what and how many that applies to. For example a generalization might be: “One pair of opposite sides are parallel.” On the polygon put markings of congruency, right angles, or parallel for the sides or angles.
