Geometry Transformations

A slide is also called a ___________.

• Translation

• Reflection

• Rotation

Translations, reflections and rotations are all known as ________________________.

• Geometry

• Transformations

• Similar

Write a rule for the translation.

• (x -1, y + 2)

• (x -2, y + 1)

• (x +2, y - 1)

Identify the transformation from ABC to A'B'C'.

• 90^o clockwise rotation

• 90^o counter clockwise rotation

• Reflection across the x-axis

Identify the transformation.

• Reflection across y-axis

• 90 Rotation counter clockwise

• Translation 5 units left, 1 unit up.

Point (-5,2) is reflected over the y axis. Where is the new point located?

• (5,2)

• (-5,-2)

• (-5,2)

Apply the following rule to the point (-5,6):

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

• (-5,-6)

• (5,-6)

• (5,6)

Which rule would result in a translation of 2 units left and 3 units up?

• (x, y) → (2x, 3y)

• (x, y) → (x - 2, y + 3)

• (x, y) → (x + 2, y - 3)

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

• (-4, 4)

• (-10, 2)

• (-4, -5)
