An angle is a figure formed by two lines or rays connecting at a common point called a vertex.

We identify angles based on the amount of space there is between the two lines. We measure this space in degrees (°) or radians - we'll be using degrees in this lesson.

There are six different types of angles based on size. To keep track of them, we imagine angles as stick figures in motion.

Pick an angle:
