1. 5.4 Quadrilaterals Objectives: Review the properties of quadrilaterals.

2. Quadrilaterals Parallelograms Trapezoids Rhombi Rectangles Squares Isosceles Trapezoids Kites Quadrilaterals

3. Facts about our shapes Quadrilaterals –4 sides –All four angles sum to 360° Parallelograms –Opposite sides parallel –Opposite sides congruent –Opposite angles congruent –Consecutive angles supplementary –Diagonals bisect each other Rectangle –All angles 90° –Diagonals congruent Square –All sides congruent

4. Facts about our shapes Quadrilaterals –4 sides –All four angles sum to 360° Parallelograms –Opposite sides parallel –Opposite sides congruent –Opposite angles congruent –Consecutive angles supplementary –Diagonals bisect each other Rhombi –All sides congruent –Diagonals are perpendicular –Diagonals bisect their angles

5. Facts about our shapes Quadrilaterals –4 sides –All four angles sum to 360° Trapezoids –Exactly one pair of parallel sides –Median (midsegment) is parallel to the bases –Median (midsegment) length is average of the bases Isosceles Trapezoids –Non parallel sides are congruent –Base angle pairs are congruent –Diagonals are congruent

6. Facts about our shapes Quadrilaterals –4 sides –All four angles sum to 360° Kites –Two pairs of distinct, congruent, adjacent sides
