Unit 6 Geometry Overview

In This Unit you will be focusing on 2D and 3D shapes. We will first review right triangles with pythagorean theorem and trig then move into non right triangles. by the end of this unit you should be able to...

Find missing side lengths and angle measures of both right and non right triangles
Calculate sector length and area of a circle
Find area of 2D shapes
Calculate volume of 3D shapes including complex figures
Find surface area of 3D shapes

Review 1: Pythagorean Theorem Review

Pythagorean Theorem

Practice for pythagorean theorem (page 105)

Review 2: Right Triangle Trigometry

This lesson has 2 videos. part 1 is a review of trig and part 2 jumps directly to exaple problems. Make sure you complete the practice problems below in your journal on page 107.

Part 1

Part 2

Practice for trigonometry (page 107)

Review 3: Inverse Trigonometry

In this lesson we are reviewing how to solve for a missing angle in a right triangle using inverse trigonometry.

Complete the notes on page 108.

Once you are done with notes, complete the practice problems below on page 109.

After this lesson you are ready to start the mastery check.

Practice for Inverse Trig (page 109)

Mastery Check for review Lessons (pg 110)

This mastery check will be 3 formative grades in total. Each section is a grade.

Pythagorean theorem
Right Triangle Trig
Inverse Trig

Make sure your calculator is in degree mode.

You will have mastered these objectives when complete:

SWBAT find the missing side or angle of a right triangle using inverse trig, right triangle trig, or pythagorean theorem.
SWBAT determine when to use inverse trig, right triangle trig, or pythagorean theorem based on the given information on a right triangle.

Lesson 1: Cosine Rule (page 111)

Below are the slides I go through in the video if you would like to view them before taking notes. By the end of this lesson you should be able to find the missing side or angle of a non right traingle using Laws of Cosine (Cosine Rule)
