Transformations

Translations

150

What happens when a shape is translated?

It slides

250

Going left and right means moving on the x or y axis?

x axis

350

Translate the point ( -1 , 3 ) to the left 2 and up 3. What is the new point?

(-3 , 6 )

450

Translate point ( -4 , 6 ) up 2 and down 3. What is the new point?

( -2 , 3 )

550

Translate points A and B to the left 2 and up 3. What are the new points?

A: ( 2 , 1 )

B: ( -1 , -2 )

A' = ( 0 , 4 )

B' = ( -3 , 1 )

Reflections

150

If a shape is in quadrant 2 and is reflected across the x axis, what quadrant will the image be in?

Quadrant 3

250

When you reflect across the y axis what happens?

The sign of the x coordinate changes

350

Reflect point (-2 , 3 ) across the y axis. What is my new point?

( 2 , 3 )

450

A shape in quadrant 1 is reflected across the x axis and then across the y axis. What quadrant will the new image be in?

Quadrant 3

550

Reflect this point across the y axis and then the x axis.

( -3 , 2)

 ( 3 , -2)

Rotations

150

What is step 1 for both types of 90 degree rotations?

Flip the x and y

250

What is the rule for a rotation of 180 degrees clockwise and counter clockwise

Change the sign of the x and y coordinate

350

Rotate this point 180 degrees clockwise (-2 , 2 ). What is the new point?

( 2 , -2)

450

Rotate point ( 1 , 2 ) 90 degrees counter-clockwise. What is the new point?

(-2 , 1 )

550

Rotate the following points 90 degrees clockwise 

(they are in the same quadrant).

A: ( 2 , -3 )

B: ( 3 , -1 )

A' = ( -3 , -2 )

B' = ( -1 , -3 )

Rigid Transformations /Sequence of Transformations

150

Give me an example of a rigid transformation.

Any type of transformation will be accepted.

250

YES OR NO....After a rigid transformation are both shapes congruent?

Yes

350

What is the definition for a sequence of transformations?

Completing transformations in a certain order that is given.

450

Translate this point to the right 3 and up 1. Then reflect it across the y axis.

( -4 , -5 )

( 1 , -4 )

550

What type of transformation would cause a point to change from ( -2 , -1 ) to (2 , 1 ). Be specific!

180 degree rotation

Coordinate Plane/Quadrants

150

How many quadrants are in a coordinate plane?

4

250

A shape is in quadrant 2 and is rotating clockwise 180 degrees. What is the new quadrant for this shape after the rotation?

Quadrant 4

350

What is the sign (negative or positive) for the x and y coordinates that are plotted in quadrant 3?

The x and y are negative

450

A shape is in quadrant 3 and is reflected across the  x axis. What quadrant will the image be in?

Quadrant II

550

A shape is plotted in quadrant 1. It is rotated 180 degrees clockwise, rotated 90 degrees counter-clockwise, and reflected across the x axis. What quadrant will the new shape be in?

Quadrant I
