1. 7.7.4 Quadrilaterals

2. Vocabulary Quad = Four Lateral = Side
Quadrilateral = Shape with four sides

3. Quadrilaterals
Quadrilateral
Trapezoid
Parallelogram
Kite

4. Quadrilaterals Quadrilateral – Shape with four sides
Kite - Quadrilateral with two pairs of congruent adjacent sides and opposite sides that are not congruent
Trapezoid - Quadrilateral with one pair of parallel side
Parallelogram - Quadrilateral with opposite sides that are parallel and congruent

5. Parallelograms
Parallelogram
Rectangle
Rhombus
Square

6. Parallelograms Rhombus - Parallelogram with four congruent sides
Square - Parallelogram with four equal sides and four right angles
Rectangle - Parallelogram with four right angles

7. Quadrilateral
Four-sided shape

8. Kite

14. Classify the Quadrilateral

15. Classify the Quadrilateral
Quadrilateral – Shape with four sides
Kite - Quadrilateral with two pairs of congruent adjacent sides and opposite sides that are not congruent
Trapezoid - Quadrilateral with one pair of parallel side
Parallelogram - Quadrilateral with opposite sides that are parallel and congruent
Rhombus - Parallelogram with four congruent sides
Square - Parallelogram with four equal sides and four right angles
Rectangle - Parallelogram with four right angles

16. Quadrilateral Angle Measurements
NOTE: the 360° total of a quadrilateral makes sense: two triangles (angle total of 180°) placed next to each other make a quadrilateral.
The four angles of ANY quadrilateral add up to be 360 degrees.
