Rotation

100

What is a rotation?

Turning or spinning an object 

200

Rotating 90 degrees clockwise is equivalent to what counterclockwis?

270 degrees

300

Rotate (3,7) and (9,2) 180 degrees counterclockwise. 

(-3,-7) (-9,-2)

400

Given these points, (3,7) and (9,2), what degree of rotation would it take to get these points, (-3,-7) and (-9,-2)

180 degrees counterclockwise 

Reflection

100

What is reflection?

When you flip across the y-axis, x-axis, y=x, y=-x.

200

Reflect the endpoint (2,-4) across the y=x axis

(-4,2) 

300

An image ABC is reflected across the y-axis. A is (2,3), B is (4,6), and C is (2,6). Where is the pre-image located?

(2,-3) (4,-6) (2,-6)

400

The image ABCD was reflected across the x-axis then the y-axis. A” is (-2,-3), B” is (-4,-4), C” is (-4,-5), and D” is (-2,-6). What is A’ B’ C’ and D’

A’ (2,-3) B’ (4,-3) C’ (4,-16) D’ is (2,-6)

Translate

100

When you translate, which direction do you move?

Up, down, right, left

200

What is the definition of translation?

Moving an object without affecting its mass

300

(4,-3) given the coordination. If you were to translate 3 down and 5 left what would the new coordinate be? 

(-2,-6)

400

A (6, 5) B (2,5) C (2,7)
A’ (2,3) B’ (2,-2) C’ (4,-2)

determine the translation.

3 down and 3 left.

Dilate

100

What does dilation mean?

Changing the size of an object.

200

What does it do?

It makes an object smaller or larger.

300

Dilate ABC by 4 inches.

A (2,3) B (2,6) C (5,3)

A’ (8,12) B’ (8,24) C’ is (20,12)

400

Given the last answers Coordinates (8,12) (8,24) and (20,12), find the Dilation it would take to get these coordinates: (0.5, 0.75) (0.5,1.5) and (1.25,0.75)

A Dilation of 1/4
