Dilation

100

What is dilation?

the action of making an object bigger or smaller

200

When scale factor is less than 1 your image becomes ?

smaller

300

If an image after a dilation centered at the origin (0,0) with scale factor “k” what is the point?

P’(ky,ky)

400

If a dilation with center of dilation C & scale factor “k” maps every point P in a figure to a point P’ what things are true?

a) if P is the center point C then P=P’ 

b) if P is not the center point c then the image point P’ lies on CP

c) angle measures are not preserved 

Rotation

100

What is rotation 

flipping the figure 

200

What is the rule for 90 degrees counter clockwise?

(x,y) —> (-y,x)

300

What type of motion is rotation

Rigid 

400

When a point (a,b) is rotated clockwise about the origin what is 180 degrees clockwise 

180 - (x,y)—> (-x,-y)=180

Reflect

100

You can reflect about a line of 

Symmetry 

200

When an object reflected it‘s size is always the 

Same 

300

Given the point (4,-5) reflect over the line y=-x

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

(5,-4)

400

C (10,4) C’(10,-4), what is the line of reflection 

X-axis 

Translate

100

True or False: If you slide your point to the right, you do (y+2)

True

200

True or False: Translation is a rigid motion.

True 

300

Point (6,4) translate 2 units left.

(4,4)

400

Move the coordinate (12,6)  x+9, y-12

(21,-6)
