INTRO
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:
An acute angle is an angle that measures less than 90°. We can imagine the angle leaning forward to see something cute.
😅 We had trouble drawing a stick figure that...bends this way. If you have any ideas, send us sketches at support@almostfun.org!

KEY STEPS

How to Identify Angles

Step 1. Describe the angle

Step 2. Identify the angle

The angle is:
  • leaning forward to see something cute
  • less than 90°
acute angle
The angle is:
  • sitting upright
  • equal to 90°
right angle
The angle is:
  • leaning backward to work its abs
  • greater than 90° and less than 180°
obtuse angle
The angle is:
  • lying flat and straight
  • equal to 180°
straight angle
The angle is:
  • flexing and bending past a straight line
  • greater than 180° and less than 360°
reflex angle
The angle is:
  • rotated all the way around
  • equal to 360°
