2. 7-7 Quadrilaterals Course 2 Warm Up Identify the triangle based on the given measurements. 1.3 ft, 4 ft, 6 ft 2. 46°, 90°, 44° 3. 7 in., 7 in., 10 in. scalene right isosceles

3. 7-7 Quadrilaterals Course 2 Problem of the Day One angle of a parallelogram measures 90°. What are the measures of the other angles? all 90°

4. 7-7 Quadrilaterals Course 2 Learn to name and identify types of quadrilaterals.

5. 7-7 Quadrilaterals Course 2 Insert Lesson Title Here Vocabulary parallelogram rhombus rectangle square trapezoid kite

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

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

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

9. 7-7 Quadrilaterals Course 2 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.

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

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

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

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

14. 7-7 Quadrilaterals Course 2 Additional Example 1B: Identifying Types of Quadrilaterals Give all the names that apply to the quadrilateral. 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.

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

16. 7-7 Quadrilaterals Course 2 Try This: Example 1A Give all the names that apply to the quadrilateral. 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.

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

18. 7-7 Quadrilaterals Course 2 Try This: Example 1C Give all the names that apply to the quadrilateral. 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.

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

20. 7-7 Quadrilaterals Course 2 Additional Example 2B: Recognizing Relationships Between Quadrilaterals Tell whether the statement is true or false. Explain your answer. 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.

21. 7-7 Quadrilaterals Course 2 Additional Example 2C: Recognizing Relationships Between Quadrilaterals Tell whether the statement is true or false. Explain your answer. 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.

22. 7-7 Quadrilaterals Course 2 Try This: Example 2A Tell whether the statement is true or false. Explain your answer. 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.

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

24. 7-7 Quadrilaterals Course 2 Try This: Example 2C Tell whether the statement is true or false. Explain your answer. 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.

25. 7-7 Quadrilaterals Course 2 Insert Lesson Title Here Lesson Quiz: Part 1 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

26. 7-7 Quadrilaterals Course 2 Insert Lesson Title Here Lesson Quiz: Part 2 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.
