Performing transformations

The red triangle represents what type of rotation:

• 90° clockwise
• 90° counter clockwise
• 180° counter or clockwise

Which of the following is NOT an isometry?

• 
• 
• 
• 

What is a rigid transformation?

• a transformation in

  which the size changes and shape of the figure does

  not change.

• a transformation in

  which the size and shape of the figure does

  not change.

• a transformation in

  which the shape changes and size of the figure does

  not change.

• a transformation in

  which the both the size and shape of the figure changes.

Identify the transformation from B to A.

• 90^o Counter Clockwise Rotation
• 180^o Rotation
• 270^o Counter clockwise Rotation
• 360^o Rotation

Describe the transformation.

• Reflect over the x-axis

• Reflect over the y-axis

• Rotate 180 degrees

• Translate to the left 2 units

Point B is reflected across line segment CD such that it maps onto point A. Points B and A are then connected to form line segment BA. Which of the following must be true?

•  $\overline{AE\ }\cong\overline{\ EB}$  

•  $\overline{CE\ }\cong\overline{\ ED}$  

•  $AB\ =\ 2\ \times\ CE$  

•  $\overline{AB\ }\cong\overline{\ CD}$  

Check all that apply. Which transformation below are considered rigid transformations?

• Translation

• Rotation

• Dilation

• Reflection
