Select the only two algebraic representations that can work for a reflection

• 
• 
• 
• 

How can this transformation be represented algebraically?

• (x + 4, y)

• (-x, -y)

• (-x, y)

• (y, -x)

This figure is rotating...

• 270^o clockwise

• 270^o counterclockwise

Which of the following images shows a rotation of 180^o?

• 
• 
• 
• 

Answer explanation

A 180 degree rotation is half of a full rotation, so it will result in a figure being rotated upside down and in the opposite quadrant of the graph.

A rigid motion ...

• preserves size and location
• preserves shape and location
• preserves size and shape
• makes the figure larger

What type of rotation does this represent (from red to blue)?

• 270⁰ C

• 360⁰
• 90⁰ CC

• 180⁰
