Introduction to transformations and rigid motions

Determine how to translate triangle ABC to triangle A'B'C'.

• right two, down five
• right two, down 9
• left two, up 9
• left two, down 5

A turn is also called a ___________.

• Translation
• Reflection
• Rotation
• Transformation

Translate the point A (-3, 4) right 5 and up 1

• (-2, 9)
• (-8, 5)
• (8, 3)
• (2, 5)

A flip is also called ___________.

• Translation

• Reflection

• Rotation

• Transformation

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
• slide left 3, right 2

The original figure prior to a transformation.

• Pre-image
• Image

What rule describes the translation?

• (x - 6, y + 2)
• (x - 2, y + 6)
• (x + 2, y - 6)
• (x + 6, y - 2)

A rigid motion ...

• preserves size and location
• preserves shape and location
• preserves size and shape
• makes the figure larger

Which of the following is NOT a rigid motion?

• Rotation

• Reflection

• Translation

• Dilation

True or False: Rigid motions preserve angle measure.

• True

• False
