A Translation is....

Objects moving left, right up or down

100

True or False: To reflect over the X-AXIS, You should change the sign of the X-VALUE of the Ordered Pair. 

False. Change the sign of the Y-VALUE in the Ordered Pair to reflect over the X-AXIS.

100

Describe the translation (X+3, Y+3)

3 Units to the Right and 3 Units Up. 

100

Write the rule:

Two Units to the Right and Three Units Up. 

(x,y) -> (X+2, Y+3)


100

Translation or Rotation?

Translation! The direction of the image is the same and it is congruent. 

200

Is this transformation a translation?

Yes.

200

True or False: To reflect over the Y-AXIS, You should change the sign on the X-VALUE in the ordered pair. 

True. 

200

Describe the translation (X+7, Y-3)

Seven Units to the Right and 3 Units Down 

200

Write the rule: Five Units to the Right and Seven Units down. 

(x,y) -> (X +5, Y-7)


200

Write the rule


(x,y) ->(X+5, Y-2)

300

True or False: A Transformation is changing a figure into another figure.

True

300

True or False: This is not a reflection. 

False. It is a reflection. 

300

Describe the translation 

(X-5, Y+2)

Five units to the left and Two Units Up 

300

Write the rule: Eight Units left and Three Units Up. 

(x,y) -> (X-8, Y+3)


300

Use a piece of graph paper:

- Plot the following points to make a triangle. A (1,1), B (-3, -2), C (3,-2). 

- (x,y) -> (x+2, y-1)

- What are the new coordinates for triangle A'B'C'?

A' (3,0), B' (-1, -3), C' (5, -3)

400

What movement does the x control?

Left and Right

400

Name this type of Reflection. 

Reflection over the Y Axis

400

Describe the translation  

(X-3, Y-6)

Three Units to the left and 6 Units Down. 

400

Write the rule: Nine Units Left and Four Units Down. 

(x,y) -> (X-9, Y-4)


400

Use a piece of graph paper.

- Plot the Points for the square ABCD: A (2,2), B (6, 2), C (2, -6), D (6,-6).

- Reflect the square over the Y Axis. 

-What are the new coordinates for square A'B'C'D'?

A' (-2,2), B' (-6,2), C' (-2, -6), D' (-6,-6)

500

Write if the movement is left, right, up or down

X+ _________

X- __________

Y+ __________

Y- ___________

X+ Right

X- Left

Y+ Up

Y- Down

500

Which letters would be considered as reflections over the X-AXIS? 

Reflections over the X AXIS: B&Z, A&O


500

True or False: This is a translation sentence (2x, 3-y)

False. NO! Translation Sentences are adding or subtracting only

500

True or False: When writing a Translation Sentence; it is okay to write it as (x,y) -> (Y+2, X+5). 

False. It will always be formatted as (x,y) -> (X____,Y___). 

500

Use a piece of graph paper.

- Plot the Points for the square ABCD: A (2,2), B (6, 2), C (2, -6), D (6,-6).

- Reflect the square over the X Axis. 

-What are the new coordinates for square A'B'C'D'?

A' (2, -2), B' (6, -2), C' (2, 6), D' (6, 6)
