Math Antics: Angle Basics

Take a linear approach to acquaint the class with angles. The video introduces the idea of angles from the notion of intersecting lines. Using the idea of perpendicular lines, the resource defines right, acute, and obtuse angles...

A straightforward lesson explains the meaning of complementary and supplementary angles. The instructor uses both an algebraic representation and a numeric example to describe each angle pair.

How do you determine the size of an angle? Pupils learn about degrees and how to measure the size of an angle. The video associates the measurements to types of angles such as acute, obtuse, and right. The additive properties of angle...

It's time to put the angles in place. Using diagrams, the video presents the basic definitions of the four classifications of angles. The segment in an informative playlist on basic geometry also provides informal descriptions of the...

Complement the angle definition. The resource, a video within a basic geometry playlist, introduces the definition of complementary angles. Using the definition, the presentation finds complements of given angles.

Develop a degree of measurement. With the aid of a protractor, the video shows how to measure angles. The segment of a larger playlist on geometry basics points out that it is possible to start at a value other than zero when measuring...

Half at one end becomes proportional on the other. As part of a basic geometry playlist, the video introduces the Angle Bisector Theorem. The presentation uses the theorem to find missing lengths in triangles.
