Classifying and Drawing Angles

This video tutorial teaches how to classify and draw different types of angles by understanding their properties. It begins with an introduction to rays, which are essential in forming angles. The tutorial then explains right angles, acute angles, and obtuse angles, highlighting their unique characteristics and how to measure them using a protractor. The importance of recognizing angles regardless of their orientation is also emphasized.

What is a ray in geometry?

• A part of a line with two endpoints

• A curved line

• A line that extends infinitely in both directions

• A part of a line that has one endpoint and extends infinitely in one direction
