Rotations, Translations, Reflections, and Dilations

A rotation is a __________ of a point, line, or figure on a coordinate plan.

• flip

• slide

• enlargement or reduction

• turn or spin

We've talked about and practiced 3 out of the 4 transformations. They are:

• dilations, translations, and reflections

• reflections, rotations, and dilations

• translations, reflections, and rotations

• rotations, dilations, and translations

What do translations, reflections, and rotations have in common?

• they all produce congruent figures

• they all slide a figure on a coordinate plane

• they all produce mirror like images on a coordinate plane

• they all turn a figure on a coordinate plane

A car driving down a straight road is an example of a _________.

• rotation

• reflection

• translation

• dilation

• (1, -2)

• (-1, 2)

• (-1, -2)

• (1, 2)

Describe the translations that were applied to quadrilateral ABCD when it was translated to quadrilateral A'B'C'D'

• down 1 unit, left 5 units

• down 4 units, left 9 units

• 5 units right, 1 unit up

• 9 units right, 4 units up

What sequence of transformations will get you from figure 1 to figure 3?

• reflection, then rotation

• rotation, then translation

• reflection, then translation

• Translation, then reflection

• Rotation, then rotation

• rotation, then dilation

• translation, then reflection

• reflection, then rotation

Identify the transformation of figure PQRSTU to figure P"Q"R"S"T"U"
