How do you tell apart the pre-image (original) and the image (copy)?
The image (copy) will have prime markers.
Point A --> Point A'

If a shape is rotated, the measure of angles will change. True or False?
False!
The shape, angles, and size will all stay the same.

What is the line of reflection in this image?
The x-axis

What are the 3 types of rigid transformations?
Translations, Rotations, Reflections

If the measure of angle 2 is 65 degrees, what is the measure of angle 3?
65 degrees - Vertical Angles
200
Describe the translation
4 Right, 5 Down

If I rotate triangle ABC 270 degrees clockwise and then rotate 90 degrees counter clockwise, I will end in the same location I started. True or false?
False!
You would need to rotate 360 degrees in the same direction.
200
If I reflect point A over the y-axis, then over the y-axis AGAIN, I will end in the same spot I started. True or False?
True
200
Are these 2 shapes congruent? How do you know?
Yes- The shapes were just reflected which is a rigid transformation.

What are 3 traits of congruent shapes?
Same Shape
Same Size
Same Angles
300
If the measure of angle 4 is 150 degrees, then what is the measure of angle 6?
30 degrees
400
What is the transformation in (x,y) form?
(x+6, y-3)

Point A is located at (6,1). It is then translated 8 units left and 4 units up. Then it is translated 10 units up and right 2 units. Where is A''?
A''(0,15)
A(6,1) -> A' (-2,5) -> A''(0,15)
