1. 1. Topic 9 Lesson 9-6<br />QUADRILATERALS<br />
2. 2. Figures with four sides are called “quadrilaterals”.<br />“Quad” means 4. <br />
3. 3. Quadrilaterals can be classified by their angles or pairs of sides.<br />
4. 4. “Poly” means “many”.<br />So any polygon with 4 sides is called a “quadrilateral” because it has many sides.<br />
5. 5. Let’s look at some different types of quadrilaterals.<br /> rhombusparallelogram<br /> trapezoidrectanglesquare <br />
6. 6. rectangle<br />4 right angles <br /> also called a parallelogram<br />
7. 7. rhombus<br /> opposite sides are parallel and all sides are the same length<br />
8. 8. square<br />4 right angles<br />All sides are the same length.<br />It is a parallelogram, rhombus, & a rectangle.<br />
9. 9. A square has 4 right angles. A rhombus does not.<br />What is the difference between a rhombus and a square?<br />
10. 10. So a square is also a rhombus, but a rhombus is not a square!<br />
11. 11. parallelogram<br /> 2 pairs of parallel sides<br />
12. 12. trapezoid<br /> only one pair of parallel sides<br />
13. 13. Now you can recognize quadrilaterals.<br />
