1. For each, attempt to create a counter example or find the shape is MUST be….. Quadrilateral Properties

2. Name the Quadrilateral if the diagonals are : equal, not perpendicular, bisect each other Not equal, one is bisected, and perpendicular equal, one is bisected, and not perpendicular equal, bisect each other and perpendicular Rectangle Kite Quadrilateral Square

3. Decide if True or False for the quadrilateral ABCD If AB = CD, then ABCD is a rectangle If angle A = angle B = angle C, then ABCD is a rectangle If ABCD is a square, then ABCD is a rectangle. F F T

4. Decide if True or False for the quadrilateral ABCD If the opposite sides are =, then ABCD is a parallelogram. If angle A = angle C, then ABCD is a parallelogram. If ABCD is a rhombus, then ABCD is a square. If all of the angles are equal, then ABCD is a square. T F F F
