you.3. Have notebook open to HW.4. Graph each of the shapes on the paper in front

of you. Make a new graph for each in your notebook. Label them with the shape number, “Shape #3” “Shape #7” etc.

How to use a protractor to measure angles

5. Measure and label all the angles with your protractor. Discuss with partners.

6. Calculate and label the lengths of each side in ‘units’, using the Pythagorean Theorem, if you know how. (Extra credit, but must show all calculations!)

Thursday 9/10

Have your extra credit open from yesterday…using the Pythagorean Theorem to calculate side lengths in your two shapes.

Is your planner up-to-date?

Key Ideas …. to Note (write in notebook)

•Two shapes are congruent if their shape and size are identical.•This means that their corresponding angles and side lengths are the same.•The first shape or pre-image can be superimposed directly over the final image by using rigid transformations: translation (slide), rotation (spin), reflection (flip).

How to use the Pythagorean Theorem to calculate side lengths

Do Now1. Measure and label all angles in both of your

shapes from yesterday.2. Calculate and label all side lengths on these

shapes. Use the Pythagorean Theorem with ‘units’ of measure.

3. Compare your shapes to those of your partners. Find the ones that are congruent.

Friday 9/11

Do Now1. Have HW open within a minute of the bell.

Materials out on desk for a second check.2. From Wednesday and Thursday, your two shapes

should be labeled with all angle measures and side lengths. If not, do that right away. Use the Pythagorean Theorem with ‘units’ of measure. Help your partners out.

3. Your shapes should be labeled in your notebook as they are on the paper: ‘Shape 1’…

4. Compare your shapes to those of your partners. Find the ones that are congruent.

•Turned in signed and completed syllabus.•Taken their assigned textbook home for the year.•All the required materials, every day:

•An updated planner.•See me if you have not done one of these things.

At this point everyone should have:

4. Look for a different shape that is congruent to one of yours. It should have a different shape #.

5. Write a paragraph about one of your shapes and its match.

“Shape #___ and Shape #___ are congruent because they have corresponding angles of _______, _______, _______ (and _____.) They have corresponding side lengths of ________, ________, ________ (and _______.) Therefore, their ________ and ________ are the same.”

Claim, Evidence, Reason

Monday 9/14

Top of seating chart = front of room by whiteboard

Bottom = back of room

Monday 9/14

Have the HW due last Friday (already checked) open on your desk.

Have your correction pen out.

Students explain HW & make corrections

From Friday: Write a sentence about one of your shapes and its match:“Shape #___ and Shape #___ are congruent because they have corresponding angles of _______, _______, _______ (and _____.) They have corresponding side lengths of ________, ________, ________ (and _______.) Therefore, their ________ and ________ are the same.”

Claim, Evidence, Reason

Isometric = “same” + “measurements”Isometric shapes = congruent shapes

Same angles and side lengths

Isometric transformation =rigid transformation

Open Notes Quiz

•May not use a cell phone.•May use note book.•Solo effort, not a team quiz.•Do not write on quiz question.•Bubble in completely.

Tuesday 9/15

Do Now: On a graph in your notes,draw polygon with corners

(2,2), (2,4), (4,4), (6,2)

Now rotate this around origin 90o, 180o, 270o.That’s one pre-image and three images.

Starting with the same coordinates, make a new graph, using (1,3) as your Point of Rotation (PoR).

Transformation Rules

(x, y) → (x + 3, y – 1)Pre-image transforms to Image

Take all x-coordinates, add 3 to get new x’s.-1 from all y-coordinates to get new y’s.

(x, y) → (-x, y)(x, y) → (y, x)

Wednesday 9/16

Will check HW due today, tomorrow.

You will understand it better after today’s class.

Improve it tonight.

Review for our first unit test tomorrow:Geometric Transformations

Ch. 7 Sections 1 & 2Ch. 0 Section 1

Khan Academy units:Transformations & Analytic Geometry

Do Now: List all the ways to prove two shapes are congruent. Describe the tools required.

1. 2. 3. 4. 5.

List all the ways to prove two shapes are congruent. Describe

the tools required.1. Cut out and superimpose shapes.2. Trace one shape on patty paper, rigidly translate, rotate,

reflect to superimpose on other.3. Measure angles with a protractor, compare side lengths

with a compass.4. Measure angles with a protractor, calculate side lengths

with the Pythagorean Theorem.5. Do x and y coordinates change using a rigid transformation

‘rule’?

List all types of Geometric Transformation

Translation

•Translation is a rigid transformation that slides the shape.•May be in the x- or y-direction, or both.•Can use two patty papers to translate along a Line of Translation (LoT).•Can use an ‘algebra rule’ to translate. What are these rules?

Reflection

•Reflection is a rigid transformation that mirrors a shape across a line of reflection (LoR).•Can use one folded patty paper to reflect.•Can use an ‘algebra rule’ to reflect. What are these rules?

Translation & Reflection Practice

•7 min - With your partners, answer Q’s 1-3, pp. 362 in notebook.•Be prepared to present.

Rotation

•Rigid Transformation where shapes turns around a Point of Rotation.

Dilation

•Non-rigid transformation where the x and y coordinates are multiplied by the same constant.•Makes shape grow or shrink equally in the x and y directions.•Angles stay the same, but side lengths change.

Stretch

•Non-rigid transformation where x and y are multiplied by different constants.•Shape does not grow or shrink by same amount in both directions, so that both it’s angles and side lengths change.
