Tuesday 4/29

We finished our "How Did They Make Ms. Pac-Man?" activity in class today.

We've now completed our entire unit on Transformations and will spend the next two days reviewing and preparing for Common Assessment #8, which we'll be taking on Friday.

Homework #114: Similarity Transformations worksheet
Solutions: Similarity Transformations answer key

Monday 4/28

Today we held a class discuss on what it means to be congruent and what it means to be similar, forming very specific definitions for each.

We also looked closely at the standards for these two concepts, making sure that we all understood them fully in preparation for Friday's Common Assessment #8.

8.G.2: Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.

8.G.4: Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two-dimensional figures, describe a sequence that exhibits the similarity between them.

We also started a transformations activity around Ms. Pac-Man that we'll continue tomorrow.

There is no homework.

Friday 4/25

We have now gone through all the material on transformations we will be covering. If you missed anything, be sure to review some of the old posts and visit the linked locations. Next week we will be having a common assessment that covers all transformations.

Here is this weeks extra credit:

We investigated properties of parallel lines cut by a transversal today (and the pairs of angles formed by that transversal) in Notes #63.

For those absent today, make sure to use the Notes #63 Student Sheet in conjunction with the notes published on the website. Fill it out as you go. This was very much a "discover & teach yourself" lesson.

Be sure to finish the orange Student Sheet. Here's a great website about Parallel Lines and Pairs of Angles that is really all you need to master these concepts. Be sure to be able to define and label examples of all of these terms:

Tuesday 4/15

Today we learned about the Exterior Angle Theorem with Notes #62.

Classwork: WB pgs 21-22

Wednesday 4/9

I was at the district office all day today instead of in class with you. :-(

In my absence, you took Notes #60 which covered interior angles, exterior angles, and classifying angles. You also covered the Angle Addition Postulate.  You then began working on page 15 from your blue geometry  workbook.

Homework #104: Finish page 15 from your workbook
Solutions: Workbook page 15 key

Tuesday 4/8

Today we learned about the building blocks of geometry with Notes #59.

You'll need a protractor for tonight's homework. If you don't have one at home, download this paper protractor, and cut it out.

Homework #103: Workbook pg 9
Solutions: Assignment #103 answer key

Monday 4/7

Today, you thought about and discovered congruence with Notes #58.

Today's lesson was a bit different than usual, as it primarily consisted of questions designed to guide you towards some important conclusions. Some questions have specific answers, some were more open-ended. We didn't finish the last couple of tasks in class today, so be sure to open the notes from the website and complete the last few parts.

On your homework, be sure to describe the sequences of transformations necessary to prove congruence.

Homework #102: Congruence worksheet
Solutions: Congruence worksheet answer key

Friday 4/4

Congratulations on making it through another week of translations, reflections, and rotations. If you'd like to get a jump on next week, try looking up the word "similar" and compare it to what we've already done.  Hint: Think about the transformations that would give us similar figures.

Here is this weekend's extra credit:

In class today we learned how to reflect objects about the lines y = x and y = -x with Notes #57.

Be sure to compare your notes from class with the ones posted here to ensure you'll be ready for Friday's quiz. There was a lot to copy - be thorough!

Homework #100: Perform the following transformation combinations:

1. Start with the point A at (-3, -1). Reflect that point across the line y = x. Now rotate that point 90º clockwise about the origin. Now translate that point +6 horizontally and -2 vertically. Give the coordinates of the newest point.
2. Figure ABCD has points at A (-2, 3), B (-4, 0), C (-3, -5), and D(0, 1). Rotate ABCD 180º clockwise about the origin. Now translate that image -3 horizontally and -5 vertically. Finally, reflect that image about the line y = -x. Give the coordinates of the new vertices.

Solutions: Tuesday & Wednesday HW answer key

Tuesday 3/32

Today we completed a card matching activity in pairs to practice our transformation skills. We glued our final transformation maps to create a poster of our team's solution. We'll be taking a look at some of the solutions together tomorrow.

Homework #99: Plot ΔABC with points A (3, -2), B (1, 4), and C (-1, 0).

1. Translate ΔABC 3 units right and 2 units down. Give the new coordinates of A’, B’, and C’.
2. Reflect ΔABC across the x-axis. Give the new coordinates of A’, B’, and C’.
3. Reflect  ΔABC across the x = -2. Give the new coordinates of A’, B’, and C’.
4. Rotate ΔABC 90º clockwise about the point (-2, 4). Give the new coordinates of A’, B’, and C’.
