Definitions
To make a figure grow or shrink in size in the coordinate plane
What is dilation?
True or False: Scale Factor can ONLY be applied to side lengths and NOT coordinates or angles.
What is False?
Angles directly next to each other
Angles inside the triangle are called what?
What are interior angles?
Who will win in the Teacher vs. Student volleyball game on Thursday?
Who is Teachers?
Contains an "x" and "y" value in the coordinate plane, seen as (x,y)
What is a coordinate?
When figures are the same shape and different sizes after a dilation, they are considered to be _________.
What is similar?
The total angle measure of supplementary angles
180 degrees
All the interior angles of a triangle add to equal ____
What is 180 degrees?
What is the date of today? (Month, Day, Year)
October 24, 2023
Something applied to angles/coordinates/sides to cause a figure to grow or reduce in size
What are A'(24,-12) B'(12,0) C'(12,24)?
Corresponding angles
Angles in the relative same location
See number 2
55 degrees

What are supplementary angles?
If a scale factor of 1 is applied to a figure, will the new figure increase in size, decrease in size, or remain the same size?
What is remain the same size?
Vertical angles
Angles directly across from each other from the point of intersection
32 + Angle 4 + 110 = 180. Find the value for measure angle 4
Angle 4 = 38 degrees
Mr. Cheezum's dog's name
Angles formed inside a set of parallel lines when intersected by a transversal (key phrase: opposite sides)
Coordinates at A(-2,1) B(0,1) and C(-2,-3). First, rotate 90 degrees clockwise to get A'B'C'. Then dilate by a scale factor of 3/2 with center of dilation at the origin. What are the coordinates for A"B"C"?
A"(2,3)B"(1.5,0)C"(-4.5,3)
Vertical angles, alternate interior angles, and corresponding angles are all ____________.
