What are Supplementary 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.

What do the graph of a line and its equation have in common? This is the first question the video poses to scholars as they begin watching the lesson. The instructor then explains how to use the graph to write the linear equation.

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...

Place angles in a line. Part of a playlist on basic geometry, an informative video teaches pupils the definition of a linear pair and how to identify them. Using their properties, the resource demonstrates how to solve problems involving...

Angles are identified by the measurement of their angles. Well, that would make sense. The instructor illustrates four different angles and their names by identifying their degrees. Zero to less than 90 degrees is an acute angle, while...

There are two parallel lines intersected by one straight line, what's that one line called? A transversal. There are a few more things to know about transversal lines and the angles they create. What are vertical angles? Are they...

How can two negative values create a positive slope? Rise over run, a negative divided by a negative. Watch the instructor explain just how that works.

By definition, perpendicular lines intersect and form a 90 degree right angle. Want to know how to determine if lines are perpendicular based on two linear equations? Check out their slope values. Are they negative reciprocals? Does...

How can two negative values create a positive slope? Rise over run, a negative divided by a negative. Watch the instructor explain just how that works.

Young scholars explore quantum physics by participating in several class activities. In this space-time lesson, students discuss the concepts of time traveling and the anatomy of an atom. Young scholars draw geometric figures and utilize...
