What is a complementary angle? Draw an example.
a set of angles that add up to 90 degrees.
What does a point do when you add to x?
Move right.
I rotate a shape 90 degrees clockwise. What do I do to x and y? Do I change the sign of x or y?
switch x and y, change the sign of y.
I am reflecting over the y axis. What do I do to x and y? Do I change either of them or keep them the same? Do I change the sign of x or y?
I keep x and y the same and change the sign of x
What is a scale factor?
The number you multiple all coordinates (x,y) by
What is a supplementary angle? Draw an example
A set of angles that adds up to 180 degrees.
What does a point do when you add to y?
Moves up.
I rotate a shape 90 degrees counterclockwise. What do I do to x and y? Do I change the sign of x or y?
I switch the x and y and change the sign of x.
I am reflecting over the x axis. What do I do to x and y? Do I change either of them or keep them the same? Do I change the sign of x or y?
I keep x and y the same and change the sign of y
What part of the human body is a good example of dilation.
The Eye or Pupil
What is a corresponding angle? Draw an example.
Angles that alternate among parallels and transversals.
What does a point do when you subtract from x?
Move left.
I keep x and y the same. I also changed both the x and y sign. How much will the shape rotate?
180 degrees
Is this point reflected over the x or the y axis?
If the scale factor is 4. Will the shape get bigger or smaller?
Bigger
What is a vertical angle? Draw an example.
angles that are formed across from each other at the vertex.
What does a point do when you subtract from y?
Moves down.
I rotate a shape 270 degrees clockwise. What do I do to x and y? Do I change the sign of x or y?
switch x and y, change the sign of x.
Is this point reflected over the x or y axis?
The x axis.
If the scale factor is 1/3 will the shape get bigger or smaller
Smaller
What is a alternate exterior angle? Draw an example.
Angles that are congruent but across from each other outside parallels and transversals.
How much does the x and y move for this figure?
x moves down 3 and y moves right 2
I rotate a shape 270 degrees counterclockwise. What do I do to x and y? Do I change the sign of x or y?
I switch the x and y and change the sign of y.
Reflect this image correctly over the y axis.
(-2,1), (-4,1), (-4,4), and (-2, 3)
What are the new coordinates of the shape if the scale factor is 2?
(4, 6), (4, -2), and (-6, -2)
