This document is a lesson on quadrilaterals that defines and describes different types of quadrilaterals including parallelograms, rhombuses, rectangles, squares, trapezoids, and kites. It provides examples of identifying quadrilaterals based on their properties and determining whether statements about relationships between quadrilaterals are true or false. The lesson includes warm-up problems, vocabulary, examples, and a quiz to assess understanding.

6. Some quadrilaterals have properties that classify them as special quadrilaterals. Here are six major special quadrilaterals. A parallelogram has two pairs of parallel sides. Course 2 7-7 Quadrilaterals

7. Some quadrilaterals have properties that classify them as special quadrilaterals. Here are six major special quadrilaterals. A rhombus has four congruent sides. Course 2 7-7 Quadrilaterals

8. Some quadrilaterals have properties that classify them as special quadrilaterals. Here are six major special quadrilaterals. A rectangle has four right angles. Course 2 7-7 Quadrilaterals

9. Some quadrilaterals have properties that classify them as special quadrilaterals. Here are six major special quadrilaterals. A square has four congruent sides and four right angles. Course 2 7-7 Quadrilaterals

10. Some quadrilaterals have properties that classify them as special quadrilaterals. Here are six major special quadrilaterals. A trapezoid has exactly one pair of parallel sides. Course 2 7-7 Quadrilaterals

11. Some quadrilaterals have properties that classify them as special quadrilaterals. Here are six major special quadrilaterals. A kite has exactly two pairs of congruent adjacent sides. Course 2 7-7 Quadrilaterals

12. Quadrilaterals can have more than one name because the special quadrilaterals sometimes share properties. Course 2 7-7 Quadrilaterals

13. Give all the names that apply to the quadrilateral. Additional Example 1A: Identifying Types of Quadrilaterals This figure has two pairs of parallel sides, so it is a parallelogram. It has four congruent sides, so it is also a rhombus. Course 2 7-7 Quadrilaterals

14. Give all the names that apply to the quadrilateral. Additional Example 1B: Identifying Types of Quadrilaterals The figure has exactly two pairs of congruent, adjacent sides, so it is a kite. It does not fit the definitions of any of the other special quadrilaterals. Course 2 7-7 Quadrilaterals

15. Give all the names that apply to the quadrilateral. Additional Example 1C: Identifying Types of Quadrilaterals The figure has two pairs of parallel sides, so it is a parallelogram. It has four right angles, so it is also a rectangle. Course 2 7-7 Quadrilaterals

16. Give all the names that apply to the quadrilateral. Try This : Example 1A This figure has two pairs of parallel sides, so it is called a parallelogram. It has four right angles, so it is also a rectangle. Course 2 7-7 Quadrilaterals

17. Give all the names that apply to the quadrilateral. Try This : Example 1B The figure has two pairs of parallel sides, so it is a parallelogram. 6 ft 6 ft 6 ft 6 ft It has four congruent sides, so it is also a rhombus. Course 2 7-7 Quadrilaterals

18. Give all the names that apply to the quadrilateral. Try This : Example 1C The figure has exactly one pair of parallel sides, so it is a trapezoid. It does not fit the definitions of any of the other special quadrilaterals. Course 2 7-7 Quadrilaterals

19. Tell whether the statement is true or false. Explain your answer. Additional Example 2A: Recognizing Relationships Between Quadrilaterals A. All rhombuses are squares. A rhombus has four congruent sides, but some may or may not have right angles. The statement is false. Course 2 7-7 Quadrilaterals

20. Tell whether the statement is true or false. Explain your answer. Additional Example 2B: Recognizing Relationships Between Quadrilaterals B. Not all squares are rectangles. A square has four right angles. A rectangle also has four right angles. So a square is a rectangle. The statement is false. Course 2 7-7 Quadrilaterals

21. Tell whether the statement is true or false. Explain your answer. Additional Example 2C: Recognizing Relationships Between Quadrilaterals C. Some parallelograms are squares. A square has all the properties of a parallelogram, so some parallelograms do have equal sides and right angles; however, some do not. The statement is true. Course 2 7-7 Quadrilaterals

22. Tell whether the statement is true or false. Explain your answer. Try This : Example 2A A. All squares are rectangles. A square has four right angles. A rectangle also has four right angles. So a square is a rectangle. The statement is true. Course 2 7-7 Quadrilaterals

23. Tell whether the statement is true or false. Explain your answer. Try This : Example 2B B. Some rectangles are squares. If the rectangle has four congruent sides, then it is a square. The statement is true. Course 2 7-7 Quadrilaterals

24. Tell whether the statement is true or false. Explain your answer. Try This : Example 2C C. Some trapezoids are squares. A square has two sets of parallel sides, but a trapezoid has only one set of parallel sides. The statement is false. Course 2 7-7 Quadrilaterals

25. Lesson Quiz: Part 1 Insert Lesson Title Here 1. Give all the names that apply to the quadrilateral. rhombus quadrilateral parallelogram Identify the quadrilateral described. 2. 4 right angles, 4 congruent sides square 3. only one pair of parallel sides trapezoid Course 2 7-7 Quadrilaterals

26. Lesson Quiz: Part 2 Insert Lesson Title Here Tell if each statement is true or false. Explain. 4. All quadrilaterals are parallelograms. False; a quadrilateral is any 4-sided polygon. 5. Every parallelogram is a rectangle. False; a rectangle is a specific kind of parallelogram with four right angles. Course 2 7-7 Quadrilaterals
