Translation 2

Multiple Choice

What is translation?

• Rotating an object

• Sliding/moving an object

• A mirror image of an object

In translations:

The side lengths stay the same

The angles stay the same

ALL the measurements of the shape stay the same!

Vectors:

Name this Vector

•  $\overrightarrow{QP}$  

Which vector maps A onto T(A)?

•  $\overrightarrow{SR}$ 

Three Properties of Translations

• Line segments map to line segments of the same length

• Angles map to angles of the same measure

• Parallel lines map to parallel lines

Property 1

Line segments map to line segments of the same length

Property 2

Angles map to angles of the same measure

Property 3

Parallel lines map to parallel lines

Question:

There is a translation that maps segment AB to segment CD.

The length of CD is 8 units.
