Translations Unit 2 Section 1

What is a translation? Moving a shape, without rotating or flipping it. "Sliding". The shape still looks exactly the same, just in a different place.

Example 1.) Use the translation What is the image of ?

Practice 1.) Use the translation What is the image of ?

Example 2.) Use the translation What is the preimage of ?

Practice 2.) Use the translation What is the preimage of ?

Example 3.) The vertices of Graph the image of the triangle using prime notation.

Practice 3.) The vertices of Graph the image of the triangle using prime notation.

Example 4.) Write a rule for the translation.

Practice 4.) Write a rule for the translation.

Vectors F G Horizontal component (5 units right) Vertical Component (3 units up) Initial Point The component form of a vector combines the horizontal and vertical components. So, the component form of is

Example 5.) Name the vector and write its component form A B M N

Practice 5.) Name the vector and write its component form E F
