A dilation is which of the following: 

• only an enlargement

• only a reduction

• Either an enlargement or a reduction

• Neither an enlargement or a reduction

Which type of transformation changes the shape of the pre-image?

• Dilation

• Stretch

• Rotation

How is vertex J mapped onto vertex P?

• a translation left 3 units and up 4 units

• a translation left 4 units and up 3 units

• a translation right 3 units and down 4 units

• a translation right 4 units and down 3 units

Which sequence of transformations maps rectangle WXYZ onto W'X'Y'Z'?

• 180 degree clockwise rotation about vertex W, followed by a translation 5 units left.

• 270 degree counterclockwise rotation about the origin, followed by a translation 5 units down.

• reflection across the line y = x

• translation 12 units left

Which statement is true?

• Rectangle WXYZ is congruent to W'X'Y'Z' because at least one nonrigid transformation is used to transform rectangle WXYZ since the side lengths of the rectangle are not preserved.

• Rectangle WXYZ is congruent to W'X'Y'Z' because only rigid transformations are used to transform rectangle WXYZ since the side lengths of the rectangle are preserved.

• Rectangle WXYZ is congruent to W'X'Y'Z' because at least one nonrigid transformation is used to transform rectangle WXYZ since the side lengths of the rectangle are NOT preserved.

• Rectangle WXYZ is NOT congruent to W'X'Y'Z' because only rigid transformations are used to transform rectangle WXYZ since the side lengths of the rectangle are preserved.

• A'(0,0) B'(3,3) C'(6,0)

• A'(1,1) B'(2,2) C'(3,1)
