What vocabulary term is this the definition of:
The ratio of the image to the preimage after dilating. In other words, it is the number we multiply by to enlarge or reduce a geometric figure.
Scale factor

Triangle ABC is represented by the following vertices:
A(1, 3), B(-2, -5), and C(3, -7).
After dilating, the new vertices are:
A'(4, 12), B'(-8, -20), and C'(12, -28)
How do you write the mapping notation for this dilation?
(x, y) --> (4x, 4y)

What does congruent mean?
Same size & same shape

Triangle ABC is represented by the following vertices:
A(6, 18), B(-3, -15), and C(9, -12).
It is dilated using a scale factor of 1/3. List all three new vertices as ordered pairs.
A'(2, 6), B'(-1, -5), C'(3, -4)

If (1,5) becomes (3,0) what happened to the coordinates in mapping notation?
(x + 2, y - 5)

This is the coordinate M' after the figure below is rotated 180o clockwise.
(-6, -6)?
300
The figure has been reflected over this axis.
the x-axis

What transformation is shown below? Be specific. 
Reflection over the y-axis
400
The side lengths of a given triangle are 6, 8, and 10.
Another triangle's side lengths are 12, 15, and 21.
Are the triangles similar? Why or why not?
No because the side lengths are not proportional.

This is the mapping notation of a translation that moves a figure 2 units left and 3 units up.
(x, y) → (x − 2, y + 3)
400
What is the rotation from pre image to image? 
90 degrees clockwise or 270 degree counter clockwise.
