# Angles

Contents

Measure angles and find missing angles in interesting geometry problems.

## Angle basics

What is an angle and how do we label, measure and construct them?

## Interpreting angles

Now that we know what angles are, let's dig a bit deeper and classify them and understand their properties a bit better.
Common Core Standards: 4.MD.C.7, 4.G.A.1

## Relationships between angles

Let's complement and supplement our knowledge of angles with some new geometry vocabulary. In this group of tutorials you'll learn about complementary, supplementary, vertical, adjacent, and straight angles. You'll quickly realize that the relationship bewten each of the angle types is quite logical and solving problems involving intersecting lines is a snap. Onward! Common Core Standards: 7.G.B.5
