Transformation Similarity

Which maps △ABC to a similar triangle?

Choose all correct answers.

• A similarity transformation exists that maps circle P to circle Q.

• If a similarity transformation maps circle A to circle Q, then it must include a rotation.

• All circles are similar.

• All circles are congruent.

• A rigid transformation exists that maps circle A to circle P.

Given that ΔAFG ~ ΔDRH, complete the following:

• AF

• AG

• FG

• FH

Quad OBCD is similar to Quad OHTE because:

• Quad OBCD can be reflected over the x axis and then rotated 90 degrees

• Quad OBCD can be reflected over the x-axis and then dilated about point O by a scale factor of 2.

• Quad OBCD can be reflected over the y-axis and then dilated about point O by a scale factor of 2.

• Quad OBCD can be reflected over the y-axis and then dilated about point O by a scale factor of 1/2.

ΔOBC is similar to ΔOGT because: (choose the best answer)

• ΔOBC can be dilated about point O by a scale factor of 1/2, and then rotated 90 degrees about point O.

• ΔOBC can be dilated about point G by a scale factor of 1/2, and then reflected over the x- axis

• They aren't similar

• They map to each other with similarity transformations.

What makes isometric transformations different than similarity transformations?

• Isometric transformations have the same shape AND size, similarity transformations just have the same shape.

• Isometric transformations are cooler

• Isometric transformations have the same shape AND size, similarity transformations just have the same size.

• They are the same, no differences.

Why are isometric transformations a part of the similarity transformations?

• Isometric transformations maintain SIZE, and similarity transformations maintain size too.

• Isometric transformations maintain SHAPE, and similarity transformations maintain shape too.
