Define Reflection

Mirror image of pre-image; reflection over the x-axis or the  y-axis

200
What are the rules for reflection over the x-axis? Reflection over the y-axis?
Reflection over x-axis: (x, -y) Reflection over y-axis: (-x, y)
200

19

300
Define a Rotation
The turn of a figure either about the origin or about a point
300

What are the rules for Rotation 180? 

Rotation 180: (x,y) -> (-x, -y)

300
Define Alternate Interior Angles
Angles that are within the parallel lines on the opposite sides
300

Figure ABCD is dilated with a scale factor or (0.95x, 0.95y). Explain what happens to the figure and why.

It reduces because the scale factor is smaller than 1.

Enlarge/Reduce the figure
400

Explain the rule for Dilation using example A(3,4) -> A'(9,12)

(x,y) -> (3x, 3y)

400

Define Alternate Exterior Angles

Angles outside the parallel lines on opposite sides

400

The pre image has coordinates of A(-2,2), B(-2,-1), C(3, -1) and is dilated to create the new coordinates A' (-3, 3), B'(-3, -1.5), C'(4.5, -1.5). What is the algebraic rule?

(x,y) -> (1.5x, 1.5y) or (3/2x, 3/2y)
