Illustrate Different Angles Using Models

Introduction to Angles

Angles are formed when two lines meet at a point. They are measured in degrees and are all around us — in corners, signs, shapes, and more!

There are three main types of angles you need to know:

• Right angle – exactly 90 degrees, like the corner of a square.
• Acute angle – less than 90 degrees, like the tip of a slice of pizza.
• Obtuse angle – more than 90 degrees but less than 180 degrees, like an open book.

Let’s learn how to recognize and describe these angles using real-life models!
