Pythagorean Theorem

7.1 Apply the Pythagorean Theorem

Before you learned about the relationship within triangles.

Now your GOAL will be to find side lengths in right triangles.

7.2 Use the converse of the Pythagorean Theorem

Before you used the Pythagorean Theorem to find missing side lengths

Now you will use its converse to determine if a triangle is a right triangle.

6.6 Similar Theorems Quiz

6.6 Use Proportionality Theorems

Goal: Use proportions with a triangle or parallel lines.

Proving Triangles Similar Quiz

Prove Triangles are Similar Part 2

Goal: HOw to prove triangles are similar using SAS Similarity Theorem.

NOTE: Quiz 1 Tomorrow over Proving Triangles are similar.

Do Now:

What happens when we mix AA and SSS Similarity Rules?




Extra Credit:

-There will be new rules for karaoke Battles.

You can sing or perform a song that you can relate to the material/concepts learned in class.

Ms. Garcia's Example:

I have used the word roni to help us remember how to denote/recognize similarity. (~)

....So it goes a little something like this.
