Amazing angles

This document defines and identifies three types of angles: right angles measure exactly 90 degrees and have two lines meeting at a square in the corner; acute angles are smaller than right angles and measure between 1 to 89 degrees with a triangular shape where the lines meet; obtuse angles are larger than right angles and measure between 91 to 179 degrees with a semicircular shape at the corner where the lines join. Examples and identifying features are provided to help the reader learn to recognize and classify different types of angles.
Amazing angles
- 1. (right, obtuse and acute)
- 2. • We can see angles everywhere! At school, at home outside etc. But do you know what types of angles they are? You can learn this and more by just looking at this slide! Are you ready? Then let’s begin!
- 3. This is a right angle. We know because it has two straight lines meeting and it is exactly 90 degrees. Also, we know because where the two lines meet in the corner, there is a square. Square
- 4. This is an acute angle. We know because it is smaller than a right angle. It is between 1 degrees and 89 degrees. They also have a little triangular type shape in the corner where the two lines meet. A way to remember acute angles is that small things are cute.
- 5. This is an obtuse angle. Obtuse angle are larger than right angles and more than 90 degrees. It is from 91 degrees to 179 degrees. It has a little circle or semi-circle in the corner where the two lines meet.
- 6. Well, that’s it for now! I hope this helped to understand, learn and practice angles! You can come back anytime to revise! I’ll see you then!
