Pairs of Angles

Ever wonder how a butcher creates the different types of ground beef? Young mathematicians explore the methods butchers use to create their desired ground beef quality. Given a combination of two types of meat with varying leanness,...

Investigate algebraic applications of complementary angles. Young scholars watch as the instructor describes and defines complementary angles. He then shows an example of finding an unknown value of x given expressions for a pair of...

You can't get from point A to point B if you can't find point A. Using a helpful video lesson, viewers learn how to plot points on a coordinate plane. The instructor emphasizes the vertical and horizontal distance of the x and...

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.

Pair a video with your lesson on t-tests. Viewers of an informative YouTube video, the 27th part of the Crash Course Statistics series, study two sample t-tests and paired t-tests. They see which test would be appropriate for a situation...

As one changes, so does the other. Scholars use an interactive to see how changes in the measure of one angle of a complementary or supplementary pair of angles affect the measure of the other angle. They answer a set of challenge...

Supplementary, obtuse, acute, complementary angles. It's good to know what all of these mean, but let's focus on one at a time. Complementary angles always add up to 90 degrees. So if given one angle in a complementary angle problem, the...

Complement and supplement your knowledge of angles. Young mathematicians study supplementary and complementary angle pairs using an interactive. A set of challenge questions solidifies this understanding.

Gain some perspective on linear pairs. Aspiring mathematicians adjust the vanishing point on a perspective drawing. They see the effect on linear pairs of angles and answer five challenge questions based on their observations.

Check to see if a given ordered pair is a solution to an inequality. Just plug the given values into the given inequality and do the math. If the resulting statement is true then the given ordered pair is a solution. If the statement is...
