  Simplify

Use the diagram to determine which equation can be used to find the measure of CAT.

• 180 + 125 = x

• x = 120 + 115

• 125 + x = 180

• x - 125 = 180

What is the scale factor?

• 2/3

• 4/5

• 3/2

• 5/4

In the diagram, the figure is reflected in line a. The image is then reflected in line b. Describe a single transformation that maps F to F''.

• 18° rotation about point J

• 36° rotation about point J

• 72° rotation about point J

• 90° rotation about point J

M is the midpoint of AB. If AM = x + 3 and AB = 3x –1, find MB.

• 7

• 20

• 10

• 4

An angle is bisected, forming two acute angles. Which is the best description for the angle that was bisected?

• obtuse

• acute

• acute, right or obtuse

• right or acute, but not obtuse

Which pair of lines in the diagram below are skew?

• BC and EH

• EF and HG

• AD and EF

• AB and AD

Describe the translation of point A(2, 1) to point A'(5, 3).

• (x, y) - (x – 3, y + 2)

• (x, y) - (x – 3, y – 2)

• (x, y) - (x + 3, y + 2)

• (x, y) - (x + 3, y – 2)

Find the value of each variable, given that the transformation is an isometry.

• x = 23, y = 3

• x = 3, y = 23

• x = 3, y = 18

• x = 1.5, y = 18
