What are the measures of the other angles? all 90°**7-7**Quadrilaterals Course 2 Learn to name and identify types of quadrilaterals.**7-7**Quadrilaterals Course 2 Insert Lesson Title Here Vocabulary parallelogram rhombus rectangle square trapezoid kite**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**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.**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.**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.**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.**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.**7-7**Quadrilaterals Course 2 Quadrilaterals can have more than one name because the special quadrilaterals sometimes share properties.**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.**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.**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.**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.**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**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.**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.**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.**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.**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.**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.**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.**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**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.
