Investigate Geometric Transformations

Write a rule for the translation.

•  (x -1, y  + 2)

•  (x -2, y  + 1)

•  (x +2, y  - 1)

• (x +1, y  -  2)

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

• (5,2)

• (-5,-2)

• (-5,2)

• (5,-2)

Describe the Transformation

• Translation

• Reflection

• Rotation

Identify the transformation.

• Reflection across y axis

• Reflection across x-axis

• 180 Rotation

• Translation 2 units down

Rotation Rules (clockwise):

90^o rotation: (x, y)→(y, -x)

What are the coordinates for A' after a 90^⁰ rotation clockwise?

• (1, 3)

• (3, 1)

• (3, -1)

• (1, -3)

• (x,y) → (x, y+8)

• (x, y) → (-y, x)

• (x,y) → (-x, y)
