5th Grade Math: How to Measure Angles Using a Protractor

In today's math lesson, we dive into the concept of measuring angles—a fundamental skill in geometry. Angles can be found in various shapes like squares and triangles, and they are formed when lines intersect. Understanding how to measure angles accurately is key to mastering geometry.

In this video, we cover:
The different types of angles, including obtuse, acute, right, and straight angles
How angles are measured in degrees
Step-by-step instructions on how to use a protractor to measure angles
Tips for determining which scale to use on a protractor (interior vs. exterior)

Key Learning Points:
Learn how to identify different types of angles.
Understand the function of a protractor and how to align it correctly with an angle.
Practice measuring angles using both the interior and exterior scales of a protractor.
By the end of this lesson, you'll be able to confidently measure angles using a protractor and understand the importance of accurate measurements in geometry.
