**Unit 4C - Volume and Density (2/14)**

Solutions to the study guide

DeltaMath assignment to practice the basics of slope, distance and midpoint formulas.

If you've never set up a DeltaMath account, you'll need the class code:

**325657**

**Unit 5 - Coordinate Geometry (Test will be Thu 3/14)**

Solutions to the study Guide!

**Unit 4b - Circles (Test will be Fri 1/25)**

Solutions to the study guide.

Here's a video about circle and segment properties. This guy is obnoxious, but his stuff is good.

Video discussing Converting between degrees and radians.

IF YOU WANT EXTRA PRACTICE: There's also a circles and segments practice assignment on DeltaMath

Use class code:

**325657**

**Midterm - 12/20**

Solutions to Review 3

There are videos below that cover the material on the midterm too. Maybe they'd be helpful?

I created an assignment called "Trig Practice"

DeltaMath will give you feedback after each problem. It's super helpful if you aren't understanding!

Videos:

Here's a very boring video covering the very basics of trigonometry.

A video on using trig to solve a simple problem

A video on using trig to solve word problems.

A video on simply finding trig ratios (just watch the first 5min)

**Unit 2C - Triangle Congruence & Parallelograms**

Solutions to study guide first half

Proofs Sheet Solutions

Extra Sheet from Monday in class

Triangle Similarity Clips:

On basic SSS, SAS, and AA

Triangle Congruence Clips:

4min clip on SSS & SAS

5min clip on ASA & AAS

a clip covering HL

Here's a longer clip, but it really does a good job explaining how to write a congruence statement.

And another one. Super annoying guy discusses ASA, AAS & HL.

**Unit 2B - Similarity**

Study Guide Solutions

Triangle Similarity Clips:

On basic SSS, SAS, and AA

**Unit 2A - Angle Relationships**

Study Guide Solutions

Quiz answers (not solutions)

Constructions help:

Construct a perpendicular bisector of a segment

Construct an angle bisector

Video about finding angles in an isosceles triangle

A little silly, but you need help with the very basics about angles, click here.

Helpful video about solving equations using angle relationships with parallel lines and a transversal

One more video, no solving. Just identifying types of angle relationships (corresponding, alt interior, etc)

For more practice and bonus points on your quiz (

**YOU CAN STILL DO THIS FOR PRACT, but not bonus pts)**:

Go to DeltaMath

Use class code:

**325657**

Create an account, and use your real name (or whatever we call you in class).

There's only one assignment available, it's called "Angle Relationships Practice"

There are 2 sections. You have to get 4 correct answers in the first section before moving on to the 2nd. Then 4 correct answers in the 2nd section to complete the assignment. Get questions correct and it will go quickly!

If you complete the assignment, we'll give you 5 bonus points on your quiz :)

**Unit 1 - Transformations**

So sorry that this is so late!!

Solutions to the study guide, I'll try to get the other study guide up later tonight.
