100

The original image before it is flipped or moved ?

What is pre-image

100
What do we do the reflection across?
The line of reflection.
100
We rotate this way when d<0.
What is CLOCKWISE?
100
When we move A, B, and L with any of the rigid motions, we label them...
We label them A' B' and L' .
200

A transformation in which a plane figure turns around a fixed center point.

What is rotation?

200
What do the reflections preserve?
distance, angles, and length
200

This angle of rotation creates the same image if it's rotated clockwise or counterclockwise

What is a rotation of 180 degrees

200
An angle is 65 degrees and I translate it. What is the measurement of the translated angle? Why?
It is 65 degrees because angles get preserved in translations.
300

Operations that alter the form of a figure. Examples: translations, reflections, dilations, and rotations.

What is transformations?

300
When we translate we follow the length and direction of this...
What is the vector
300
This is the new coordinates of the point P after we rotate P (a, b) around the origin 180 degrees.
What is (-a, -b)
300
If the length of a segment is 5 cm and we rotate it, how long is the rotated segment? Why?
It is 5 cm because it is preserved in a rotation.
400
This is a property of all three rigid motions, and it means to keep the same lengths, the same angles, and the same distances.
What is PRESERVE?
400
This many degrees takes us all the way around a point. Name the degrees and the shape it makes.
360 degrees... circle
