Translations
A translation is when you do this to a figure.
What is slide it right, left, up, or down?
A rotation is when you do this to a figure.
What is turn it?
When a transformation does not change the size or shape of a figure, the transformation is this.
What is rigid or congruent?
These are the three transformations that stay rigid (same size and shape).
What are translations, reflections, and rotations?
Find the new coordinates of (10,12) if you translate the point three units left.
What is (7,12)?
Find the new coordinates of (3,-2) after you reflect the point over the x-axis.

What is a dilation?
Write the algebraic expression of point (x,y) after it moves 3 spots to the left and 7 spots up.
What is (x-3,y+7)?
Write the algebraic expression of point (x,y) after it is reflected over the y-axis.
What is (-x,y)?
Write the algebraic expression of point (x,y) after it rotates 90º clockwise.
What is (y,-x)?
This is the name of the point (0, 0).
What is the origin?
This changes with a reflection.
What is orientation (or order of vertices)?
Describe the translation for this notation: (x,y) --> (x + 8, y + 4)

What is (1,6)?
These are the corners of a figure with lines.
What are vertices?
These transformations change the orientation of a figure.
