Lesson Menu Five-Minute Check (over Lesson 9–6) Main Idea and Vocabulary Example 1:Identify Similar and Congruent Figures Example 2:Identify Similar and Congruent Figures Example 3:Identify Corresponding Sides Example 4:Identify Similar Figures

Main Idea/Vocabulary similar figures congruent figures corresponding sides Identify similar and congruent figures.

Example 1 Identify Similar and Congruent Figures Tell whether the pair of figures is similar, congruent, or neither. The figures have the same shape but not the same size. Answer: They are similar.

1.A 2.B 3.C Example 1 A.similar B.congruent C.neither Tell whether the pair of figures is similar, congruent, or neither.

Example 2 Identify Similar and Congruent Figures Tell whether the pair of figures is similar, congruent, or neither. Answer: The figures are neither similar nor congruent. The figures have neither the same shape nor the same size.

1.A 2.B 3.C Example 2 A.similar B.congruent C.neither Tell whether the pair of figures is similar, congruent, or neither.

Example 3 Identify Corresponding Sides SKATEBOARDING RAMPS The two ramps shown are congruent. What side of triangle QRS corresponds to AC? Corresponding sides represent the same side of similar figures. Answer: So, QS corresponds to AC.

1.A 2.B 3.C 4.D Example 3 FLOOR TILES The two floor tiles shown are congruent. What side of rectangle ABCD corresponds to FG? A.AB B.BC C.CD D.DA

Example 4 Which rectangle below is similar to rectangle EFGH? Identify Similar Figures

Example 4 Examine the ratios of corresponding sides to see if they have a constant ratio. Answer: So, rectangle WXYZ is similar to rectangle EFGH. Identify Similar Figures Rectangle ABCDRectangle MNOPRectangle WXYZ

1.A 2.B 3.C 4.D Example 4 Which triangle below is similar to triangle ABC? A.B. C.D.
