1. Warm-Up ABCD is a parallelogram. Find the length of BC. A B C D 5x + 3 3x + 11

2. Geometry 6-4 and 6-6 Rectangles, Rhombi, Squares, Kites, and Trapezoids

3. Quadrilateral 4-sided figure

4. Parallelogram Opposite sides parallel Opposite sides congruent Opposite angles congruent Consecutive angles supplementary Diagonals bisect

5. Rectangle 4 right angles Diagonals are congruent

6. Rhombus 4 congruent sides Diagonals are perpendicular Diagonals bisect opposite angles

7. Square 4 right angles 4 congruent sides Everything a rectangle and rhombus have

8. Kite Two pairs of congruent consecutive sides Diagonals are perpendicular Middle pair of opposite angles are congruent

9. Trapezoid Only one pair of parallel sides (called bases) Non-parallel sides are called legs Base angles share a common base

10. Isosceles Trapezoid Legs are congruent Each pair of base angles are congruent Diagonals are congruent

11. quadrilateral parallelogram rectangle rhombus square kite trapezoid isosceles trapezoid
