Countdown Challenge: Complimentary/Supplementary Angles

Learners are given one angle measure, and then determine the corresponding supplementary or complementary angle. A reference web site is given for additional activities. This assignement can be adapted to demonstrate that angle measure...

A missing measure mystery! Right angles and straight angles are divided in two, with the measure of one side provided. Angle analyzers compute the value of the missing complimentary or supplementary angle. There are eight problems for...

Learners are given one angle measurement and determine either the corresponding supplementary or complementary angle measurement. A reference web site is given for additional activities.

Here is a complimentary and supplementary angles worksheet in which learners solve 12 word problems that require them to calculate the measure of angles.

Over the course of 18 problems, learners identify angles as complementary, supplementary, vertical or adjacent. They name relationships in angles such as alternate interior, corresponding, and alternate exterior angles. They apply the...

Supplement your knowledge of angles. Part of a playlist exploring geometry concepts, an interesting video introduces the definition of supplementary angles. Using the definition, the presentation shows how to find the supplement to a...

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.

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...

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...

This video provides an opportunity to learn about complementary and supplementary angles. As you watch and listen to the teacher and student interact it helps clarify the thinking behind applying this concept. [3:41]
