Honors GeometryUnit 1 - TransformationsWelcome to Honors Geometry!As you find your seat, begin working on your Student Info sheet.

When finished, read through the syllabusSyllabusLets look at it togetherGeometry BinderClassroom Procedure: Warm UpsEach 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: HomeworkYou 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.Classroom ExpectationsBe Respectful

Be Responsible

ParticipateWhat do these look like?Be Respectful8Be ResponsibleParticipateAll KHS policies will also be enforcedPlease remove hats before entering the classroom.

Thank you for respecting my time and keeping your cell phone turned off/in your locker/at home.

Please finish all food and drinks (except water) in the hall before coming in the classroom.Any other Classroom Expectations?Unit 1 - TransformationsEssential QuestionsWhat is a transformation?What are different ways the four types of transformations can be represented?

Todays ObjectivesIntroduction to class/proceduresIntroduce transformationsInvestigate translationsTransformers

Who has seen this movie? Who can describe what happens?14Bumblebee Transforming

Example15Image or Preimage?

Which is which?16TransformationA transformation of a geometric figure is a change in its position, shape, or size.

The preimage isthe original figure. (Denoted by A)

The image isthe figure after a transformation. (A of A prime)

IsometryAn 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

What is going on in this picture?

Which is the preimage? Image?20Group Work Translation WorksheetRead through the directions carefully

If you do not understand the directions, first talk with your group, then ask for help

Worksheet

TranslationA 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 NotationVector notation to write rules of transformations. Vector: describes a slide writtenx = left/righty = up/down

Formulizing Algebraic RulesPre-image Image

Describes a translation of a horizontal units (+ Right, - Left)b vertical units (+ Up, - Down)

Ask students to create this slide before providing them with this information.24 Ex 1Describe 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!!)HomeworkPractice 12-2
