An Introduction to Basic Angles
Description
This video explains the various type of angles and why each angle is classified in certain categories. Examples of uses in math and uses in the real world are provided in the video and the picture examples are organized into the different categories for angles.
Overview
Angles are points that are measured in the unit degrees. They are used often in mathematics and are seen in the shape of a triangle. There are several different types of angles. The most common ones are acute angles, right angles, and obtuse angles. The way to remember these is an acute angle = a cute angle. Small things are considered cute and small angles are acute angles. Right angles = correct angles. Something that is perfectly straight and squared off is considered to be correct, like a right angle. Once you remember these, obtuse must be the remaining angle.
Acute Angles: Angles measuring less than 90 degrees
Right Angles: Angles measuring 90 degrees
Obtuse Angles: Angles measuring more than 90 degrees
Protractors are used to measure degrees if you are curious as to whether or not your angle is acute, right, or obtuse.
