Which of the following angles would NOT be congruent to the measure of  $\angle7$ ?

•  $\angle2$  

•  $\angle3$  

•  $\angle6$  

•  $\angle8$  

If the  $m\angle7\ =\ 115\degree,$  find the measure of  $\angle2.$  

•  $115\degree$  

•  $65\degree$  

•  $180\degree$  

• Cannot be determined

Find the measure of the indicated angle. 

• 95
• 85
• 35
• 45

If m∠1 = 30°, then m∠3 = 

• 30°
• 60°
• 150°
• undetermined

Find C 

• ∠C=116°
• ∠C=64°
• ∠C=180°
• ∠C=26°

Figure ABC in the coordinate plane has vertices at (2, 1), (-6, 4), and (-3, -2). If the figure is translated 5 units to the right and 2 units up, what are the coordinates of the A'B'C'?

• (-2, -1), (-6, 4), (3, 2)

• (-3, -2), (-6, 4), (2, 1)

• (7, 3), (-1, 6), (2, 0)

• (0, 6), (-8, 9), (-5, 3)

Look at the figure below. The transformation that was used to map ABC to A'B'C' was

• Reflection across the x-axis

• Reflection across the y-axis

• Rotation 90° clockwise

• Rotation 270° counterclockwise

Lesley and Marc are designing a new logo. They start by creating a triangle shape in the lower left quadrant as shown below. They transform it by rotating the triangle shown above 90° clockwise about the origin. What does the new design look like?
