Geometry Transformation Test

The point ( -2,5) is reflected over the line x = 1.  Find its image.

• (  4,  5)

• ( -2  , -5)

• ( 2  ,  5)

• (2   , -5)

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

• Reflection across the x-axis

• Reflection across the y-axis

• 90^o clockwise rotation

• 90^o counterclockwise rotation

Identify the transformation from C to D.

• 90^o Counter Clockwise Rotation

• 180^o Rotation

• 270^o Counter clockwise Rotation

• 360^o Rotation

True or False: A reflection is an isometry.

• True

• False

True or False: A dilation is an isometry.

• True

• False

Rotate (x, y) 180˚ clockwise about the origin

• (-x, -y)

• (x, -y)

• (-y, -x)

• (y, x)

Rotate (x, y) 270˚ clockwise about the origin.

• (-y, x)

• (y, -x)

• (y, x)

• (-x, y)

A scale factor is

• a number you divide by to get the new size

• How big something is.

• A number you multiply by to get the new size

• What you use for a reflection

Dilate Point B by a scale factor of 3:

• (12,0)

• (12,12)

• (4,3)

• (0,12)

Which transformation will result in being similar to the original figure but has a larger area?

• Dilation with scale factor of 2

• Dilation with scale factor of 1

• Dilation with scale factor of .5

• Translation
