Similarity Transformation

Name the series of transformations that maps ABC onto DEF

The composition of one or more rigid motions and a dilation is called a(n)

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.

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.
