What is an angle and how do we label, measure and construct them? Great question. Luckily we have all your answers! To begin our journey towards understanding angles, we'll learn terms like vertex, acute, obtuse, circle arc, circumference, and protractor. These basic angle concepts will get you on the road to angle domination! Common Core Standards: 4.MD.C.5, 4.MD.C.5a, 4.MD.C.5b, 4.MD.C.6, 4.MD.C.7, 4.G.A.1

### Angle basics

VIDEO
6:49 minutes

The naming of an angle is related to the line segments that create it. We'll also learn about the angle's vertex. Come on. Let's do this.

### Naming angles exercise example

VIDEO
1:11 minutes

Here's an example exercise in which we find the correct angle name(s).

### Angle measurement and circle arcs

VIDEO
7:37 minutes

Did you know that the measurement of an angle is realted to the arc of a circle? Yes, indeed! Watch.

### Angles and circumference

VIDEO
1:40 minutes

We're slowly starting to put things together in this example exercise: angle, circle, circumference, and fractions. Woohoo!

### Measuring angles in degrees

VIDEO
8:22 minutes

Let's come up with an exact way to measure an angle using a protractor. We'll also learn about acute angles. Not to be confused with augly angles :)

### Measuring angles using a protractor

VIDEO
3:25 minutes

Let's use our virtual protractor to measure some angles together, shall we?

### More angle measurements using a protractor

VIDEO
4:05 minutes

We're practicing measuring angles using the virtual protractor. Do this a few times with us and you'll use a real protractor like a pro!

### Constructing angles

2:41 minutes

As opposed to measuring an angle using a protractor, in this example we're constructing an angle. Same idea here, just a slightly different application. You got this.
