Today in class we reviewed the homework on properties of parallelograms. We practiced proofs with parallelograms. Properties of ALL parallelograms (rectangles, rhombi and squares are all parallelograms): 1) opposite sides are congruent (side1 = side2) 2) opposite angles are congruent (angle1 = angle2) 3) consecutive angles are supplementary (angle1 + angle2 = 180) 4) diagonals bisect each other (diagonals are split into 2 equal parts) Additional property for rectangles & squares (all squares are rectangles): 1) diagonals are congruent Additonal properties for rhombi & squares (all squares are rhombi): 1) diagonals are perpendicular 2) diagonals bisect the angles Homework: Study for your quiz tomorrow. Complete the quiz review sheet (that is separate from your packet). Practice and review proofs. Copies of today's notes:
