If a pre-image has a point located 5 units to the left of a line of reflection, what can you tell me about that point once the figure is reflected over that line of reflection?
It is 5 units to the right of the line of reflection

What is a translation in Geometry?
A translation is a transformation that slides every point of a shape the same distance
100
What do we know is true about Supplementary angles?
They will add up to 180 degrees every time
200
What does the word congruent mean?
Same shape, same size.

If the point (1, 2) is rotated 180° around the origin, where is the new position?
(-1,-2) (You have to negate the x and y but DO NOT SWITCH THEM
200
What is the new point when (2, 3) translated by 5 units to the right and 2 units up?

What are the directions we can rotate a shape?
Counterclockwise or Clockwise
300
What is an equivalent rotation to 120 degrees clockwise?
240 degrees counterclockwise
