The video tutorial explains how to classify angles using a table format. It covers different types of angles, including acute, right, obtuse, straight, reflex, and revolution angles, and discusses the use of degrees as a unit of measurement. The tutorial also explains why 360 degrees is used for a full circle, highlighting its divisibility by many numbers.

What are the three columns used for classifying angles in the table?

• Size, Name, Diagram

• Length, Width, Height

• Color, Shape, Texture

• Type, Category, Example
