Unit 8 Practice 1 (H)

Determine whether each pair of figures is similar.

If so, which similarity transformations were used

• yes they are Similar

• No they are NOT Similar

• reflected across the Y-Axis

• Reflected across the X-Axis

• Dilated by a factor of 1.5

Determine whether each pair of figures is similar.

If so, which similarity transformations were used

• yes they are Similar

• No they are NOT Similar

• Translation 3 units right

• Dilate by a factor of 1/2

• Dilated by a factor of 2

Figure JKLM is similar to figure WXYZ. Find the length of side WZ.

Figure JKLM is similar to figure WXYZ. Find the length of side JM.

Determine whether each sequence of transformations produces a pair of similar figures.

• Yes, the figures would be similar

• No, the figures would NOT be similar

• (3x , 3y)

  would be a dilation which would be similar

• (x-4, y+3)

  would be a translation which would be similar

• (x-4, y+3)

  would be a translation which would NOT be similar

Determine whether each sequence of transformations produces a pair of similar figures.

• Yes, the figures would be similar

• No, the figures would NOT be similar

• (-x , y)

  would be a reflection which would be similar

• (x, 1/2y)

  would be a vertical compression which would be similar

• (x, 1/2y)

  would be a vertical compression which would NOT be similar

• Circle A is similar to Circle B

  because

  corresponding parts are congruent.

• Circle A is similar to Circle B

  because of the Circle Similarity Theorem

• Circle A is similar to Circle B

  because of the Circle Congruence Theorem

• Circle A is NOT similar to Circle B

• The stores DO form Similar rectangles

• The stores do NOT form Similar rectangles

• Change the width of store B to 64 feet and the rectangles will become similar

• Change the width of store B to 65 feet and the rectangles will become similar

• Change the width of store B to 67 feet and the rectangles will become similar

• A

• B

• C

• D
