1. Warm up is on the back table. Please get one and start working ♥

2. We’re going to 6.4 Rectangles, Rhombi and Squares 6.3 Proving Parallelograms and together

3. 3 pieces of cool information about parallelograms 1. If both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram. 3. If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram. 2. If one pair of opposite sides of a quadrilateral is parallel AND congruent, then the quadrilateral is a parallelogram. 4. If both pairs of opposite sides are parallel, then the quadrilateral is a parallelogram. 5. If opposite angles are congruent, then the quadrilateral is a parallelogram. 5 pieces of cool information about parallelograms

4. Four congruent sides. The diagonals are perpendicular. The diagonals bisect a pair of opposite angles. Rhombuses, rectangles, and squares Four right angles. The diagonals are congruent. Has all the characteristics of a rectangle and a rhombus

5. Here is a Venn diagram to help you see the relationships.

6. Decide whether the parallelogram is a rhombus, a rectangle, or a square.

7. List the quadrilaterals that have the given property. Choose among parallelogram, rhombus, rectangle, and square. 1.Opposite angles are supplementary. 2.Consecutive sides are . 3.Consecutive sides are . 4.Consecutive angles are .

8. Determine the measure of the numbered angles in rhombus DEFG.

9. Determine the measure of the numbered angles in each figure. rectangle ABCD square LMNO
