Rigid transformations always produces images that are WHAT to the pre-image?
CONGRUENT
100
Identify the transformation below.
Translation by DLS from C to C'.
100
In a translation, the direct line segments that map points on the pre-image to their corresponding points on the image are all ________________ to each other.
Parallel
200
What are the three types of rigid transformations?
translations, reflections, and rotations
200
The given graph depict multiple transformations of the pre-image *. This image depicts a Reflection of * across the y-axis.

Three things you need to define a rotation are...
Center of rotation
Angle of rotation
Direction of rotation

What is the notation(symbol) used to differentiate the IMAGE from the PRE-IMAGE?
prime or '
pre-image image
A A'
B B'
Triangle ABC Triangle A'B'C'
300
The given graph represents transformations of the pre-image *. This figure depicts a Rotation of the pre-image 180 degrees about the origin.
figure C
300
It's the triangle in the picture below that is a 90 degree counterclockwise rotation of triangle A.
What is triangle D?
400
Which rotation results in the same location whether it is done clockwise or counter-clockwise?
180o
400
The given graph depicts rigid transformations of the pre-image *. This triangle represents a rotation of * 90-degrees counterclockwise about the origin. 
figure B

The picture below appears to show a 180 degree rotation, but could also be described as a sequence of 2 transformations. Describe the sequence.
Reflection across the x-axis and then the y-axis
(Or vice versa)

Which construction (from our last test) do you need to perform to reflect an image across a line with your compass?
Perpendicular line to a point off the line/
Perpendicular bisector
