Classroom Procedure: Warm Ups• Each day will start with a Warm Up posted on
the board.
• Warm ups should be completed on a loose leaf piece of paper and stored in your binder.
• Multiple Warm Ups can be answered on page as long as each is clearly marked with the date.
• Warm Ups must be stored in chronological order.

Classroom Procedure: Homework• You will each have an individual Homework Stamp
Sheet
• Your Homework Stamp Sheet must be in the Homework section of your Geometry Binder.
• At the beginning of each class, while working on your Warm Up, I will walk around to check your Homework and mark your Stamp Sheet
• Homework is graded by completion. (100%, 50%, 0%). Late Homework will not be accepted but is required for your binder.

Image or Preimage?

Transformation•A transformation of a geometric figure
is a change in its position, shape, or size.
•The preimage is…the original figure. (Denoted by A)
•The image is…the figure after a transformation. (A’ of “A prime”)

Isometry•An isometry is a transformation in which
the preimage and image are congruent
•What does it mean to be congruent?▫Two figures are congruent if they have the
exact same size and shape (≅)

Arrow NotationA A’ means point A becomes A’

Group Work – Translation Worksheet
•Read through the directions carefully
•If you do not understand the directions, first talk with your group, then ask for help

Translation•A translation is an isometry
(transformation) that slides all points of a figure a fixed distance in the same direction (a slide)
Why is it an isometry?

Vector Notation•Vector notation to write rules of
transformations. Vector: describes a slide written
x = left/righty = up/down

Formulizing Algebraic Rules
Pre-image Image
Describes a translation of a horizontal units (+ Right, - Left)
b vertical units (+ Up, - Down)

Ex 1•Describe the translation that this rule
represents.

Partner Practice.• 1. On one side of your graph paper, draw lines to split
your page into three parts
• 2. In section 1, draw a preimage and create an algebraic rule so that your partner can create the image.
• 3. In section 2, draw a preimage and a translated image so that your partner can describe the algebraic rule.
• 4. In section 3, draw an IMAGE and create an algebraic rule so that your neighbor can create the PREIMAGE. (hint: you need to work backwards!!)
