300
What line could these hexagons reflect over to still be the same image?
What is the horizontal line across the center?
300
True or false: when a shape is rotated, the original shape and its image are congruent.
What is true?
300
How are rotations similar to reflections and translations? (name 1 way)
1) They are congruent to each other (don't change the size or shape)
2) They only change the orientation of the object

What is the reflection line for the letter M?
(Vertical line down the middle)
400
True or False: For every object, a 360 degree rotation would give you a image of the same orientation as the original shape.
What is True?
