what is the scale factor of the prime image

• 1/3

• 1/4

• 1/2

• 2

A turn is also called a ___________.

• Translation

• Reflection

• Rotation

• Transformation

What rigid motion from the pre-image to the prime image?

• transformation

• rotation

• translation

• reflection

Look at the graph of a line segment before and after a transformation occurred. Which statement describes the transformation that could have been made to the line segment?

• The line segment was dilated by a factor of 1/2

• The line segment was rotated by 180⁰ about the origin.

• The line segment was reflected over the x-axis.

• The line segment was translated 6 units down and 1 unit left

Parallelogram ABCD is shown on the coordinate plane. Parallelogram ABCD will be reflected over the x-axis to create parallelogram A'B'C'D'.

What are the new coordinates of point C' after the reflection of parallelogram ABCD?

• 6, 3

• -6, 3

• 6, -3

• -6, -3

Parallelogram ABCD is shown on the coordinate plane. Parallelogram ABCD will be reflected over the x-axis. Then, it will be rotated 90⁰ counterclockwise about the origin to create parallelogram A"B"C"D".

What are the new coordinates of point B' after the series of transformations?

• 3, 2

• 2, 3

• 2, -3

• -3, 2

A line segment on a graph has endpoints of (-3, 1) and (3, 1). It is translated 5 units down and then reflected across the x-axis.

What are the endpoints after the series of transformations?

• (-3, -4) and (3, 4)

• (-3, -1) and (3, -1)

• (-3, 4) and (3, 4)

• (-3, -6) and (3, -6)

What sequence of transformations can be applied to triangle ABC to show that it is congruent to triangle DEF?

• reflect across the x-axis
