Pre Algebra Translations

How do the points of a figure move in a translation?

• Same distance and different direction

• Same distance and same direction

• Different distance and different direction

• Different distance and same direction

Is Figure A'B'C'D' a translation of Figure ABCD?

• Yes

• No

Find C' after a translation using this rule: (x, y)-->(x + 3, y + 1)

• (3, 4)

• (4, 2)

• (5, 2)

• (4, 3)

What is the rule that describes the translation that maps ∆LMN to ∆L'M'N'?

• 3 units right and 4 units up

• 3 units left and 4 units up

• 3 units right and 4 units down

• 3 units left and 4 units down

Which figure is a translation of Figure I?

• Figure A

• Figure B

• Figure C

• None of the above

Is Figure A'B'C'D' a reflection of ABCD over line f?

• Yes

• No

Which of the following statements is true about the values of the coordinate points in a figure when it is reflected over the y-axis?

• Only the x-values remain the same.

• Only the y-values remain the same.

• Both the x and y values remain the same.

• Both the x and y values change.

∆ A'B'C' is a reflection of ∆ ABC. Which choice best describes the reflection?

• A reflection over the line x = 2

• A reflection over the line y = 3

• A reflection over the line x = 3

• A reflection over the y-axis

The vertices of ABCD are A(1, 1), B(2, 3), C (4, 3), and D(5, 1). If figure ABCD is reflected over the line y = -1, find the coordinates of vertex B'. (BTW... a vertex is a point!)

• (-4, 3)

• (2, 2)

• (-2, 3)

• (2, -5)

Find K' if the figure is reflected across the x-axis

• (4, 1))
• (-1, -4)
• (1, -4)
• (1, 4)
