Translations/Reflections

100

Describe the translation:

A (1,2)     A'(-1,-5)

Left 2 Down 7

Point A is at (-3,-1). What is the image of A' after it is translated 8 units right and 5 units down.

A' (5,-6)

LOSS OF POINTS

If you get the next question right, you will not lose points. If you get the next question wrong, you will lose double the points that the next question is worth.

Coordinate Notation

100

Name the transformation

(x+a, y+b)

Translation

200

Name the transformation:

(x,y) => (x,-y)

Reflection over the x-axis

300

Name the transformation

(x,y)=>(y,x)

Reflection over y=x

400

Name both transformations

1. (x,y)=>(-y,x)

2. Reflection over y=-x

1. 90 degrees counterclockwise

2. (x,y)=>(-y,-x)

500

Name BOTH transformations

1. (x,y)=>(y,-x)

2. (x,y)=>(-x,-y)

1. 270 degrees counter clockwise

2. 180 degrees counter clockwise

Dilations

100

True or False: If the size of an image decreases, you divide by the scale factor.

FALSE, never divide the scale factor, always multiply.

200

Give 2 examples of scale factors. The first one makes the image size increase, the second one makes the image size decrease. 

Increase should be greater than 1.

Decrease should be between 0 and 1. 

300

What is the scale factor for the following transformation. A'(-12,6) A is (-4,2)

Scale factor of 3 

400

Dilate (-8,8) by a scale factor of 3/4.

(-6,6)

(-5,6)

300
