Translations & Rotations Review

State the line of reflection.

• Reflection across y-axis

• Reflection across x-axis

• Reflection across x = 1

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

• (4, 1))

• (-1, -4)

• (1, 4)

Reflect the point (2, -4) over the y-axis.

• (-4, 2)

• (-2, 4)

• (-2, -4)

∆QRS contains the points: Q(4, 2) R(5, 1) S(3,7). If the triangle is reflected across the y-axis, what will S' be?

• S'(3, 7)

• S'(-3, 7)

• S'(3, 7)

Which answer shows a reflection across the x-axis?

• d

• c

• b

Determine where X' would be if you translated 3 units to the left and 9 units down.

• (-4, 4)

• (-10, 2)

• (-4, -5)

How is triangle ABC being translated to triangle A'B'C'?

• up 3, left 8

• up 9, left 4

• down 9, right 4

What transformation is happening?

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

• slide up 2, left 3

• slide right 2, up 3

• slide right 2, down 3

Write the rule for this translation:
Slide 3 up and 2 right

• (x, y)---->
  (x + 3, y + 2)
• (x, y)---->
  (x+2, y + 3)
• (x, y)---->
  (x - 2, y + 3)

What is a reflection?

• When you turn an object around a point.

• When you slide an object form one place to another.

• When you flip or mirror an object across a line.
