Geometry Lesson 1.10 and 1.11

A slide is also called a _________.

• Translation
• Reflection
• Rotation
• Transformation

 Describe the Transformation

• Translation
• Rotation
• Reflection

• A

• B

• C

• D

Select all that are true

• Point P perpendicular to L

• Point P is on line L

• P' and P are the same point

• P does not have an image

Which of the following best describes how to reflect a point P over a Line L

• Flip point P over line L

• Construct a circle centered at P and mark the intersection Q of Circle P and Line L. Draw a perpendicular line to Q and mark it R. Point R is the reflected point

• Construct a line through P that is perpendicular to L. Mark the intersection point of the two lines Q. Draw a circle center at Q with radius PQ. P' is the intersection of circle Q and line L

True or false: When you apply two or more rigid transformations to a figure, the image will be the same no matter what order the transformations are applied

• True

• False

When describing a rotation, you need to state

• center of rotation

• the radius

• the angle and direction (clockwise or counterclockwise)

• the vector (directed line segment)
