Supplementary Angles Teacher Resources

How can geometry learners remember the difference between supplementary and complementary angles? Not only will the video explain how to remember these two angles, but it also demonstrates how to find unknown angles knowing the degree of...

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...

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...

Connect algebraic and geometric concepts to solve problems. The first lesson in the 29-part series examines complementary and supplementary angle relationships. Scholars write equations to represent the relationships and solve for...

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.

The itsy, bitsy spider went up the virtual wall. An interactive allows users to change the angles in a spider web. They must attend to supplementary angles as they answer challenge questions throughout the interactive.

In this complementary/supplementary angle instructional activity, students explore the definition of complementary and supplementary angles. They demonstrate models of a complementary and a supplementary angle. This is a one-page...

Learners investigate complementary and supplementary angles. They use dynamic geometry (TI-nspire) software to manipulate rays to identify the conditions necessary to create complementary and supplementary angles.  They find the measure...

Practice recognizing types of additive angles with a activity in which pupils review adjacent, interior and exterior, complementary, and supplementary angles and use a diagram to give examples of them. Be aware that the diagram involves...

This splendid assignment gets future engineers to compute complementary or supplementary angles in real-life applications! Once they have mastered the art of additive angles, they can apply their knowledge to help Steve, Inez, Carlotta,...

Explore with your class the characteristics of acute, obtuse, right, complementary, and supplementary angles. They take digital photographs around the school and identify the angles in the images. Uisng software, they label and print the...

What makes vertical angles so special? Here's a few words that might help you figure out why: intersecting lines, congruent angles, opposite, supplementary angles. Still wondering? Then watch this video for a good explanation of vertical...

What are supplementary angles? They are two angles that when added together make 180 degrees on a straight angle line. Hard to picture that? Then watch this video and see how the instructor illustrates this on a diagram.

How can a straight line be called a straight angle? Can angles be combined to form a straight angle? Yes, supplementary angles can be combined to make a straight angle and that is how one can find the value of a missing angle. Take a...

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

Learners address 14 questions that include naming all pairs of opposite and supplementary angles for sets of intersecting lines and then, finding the measure of the unknown angle. They determine the measure of the angle that is...

Introduce your learners to angles using the Leaning Tower of Pisa for inspiration and focus. Small groups work together to determine if pairs of angles are complementary or supplementary.They view drawings of angles (vertical, adjacent,...

Pupils calculate the measurement of supplementary angles when one angle is known. The one-page assignment has six simple problems. It contains links to related resources as well as the answer key. Be aware that although the publisher...

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...

Your geometry learners determine the measure of remaining angles in sets of three given that the other two are complementary or supplementary. From a diagram, they identify which angles are supplementary, complementary or congruent from...

In this geometry worksheet, 10th graders find the missing angles in a pair of supplementary angles.  The one page worksheet contains six problems.  Solutions are provided. 

What are the exterior angles of a polygon? Polygons have exterior angles? How? Oh, extend all the lines, and find the value of each of the supplementary angles. No problem as long as one knows what supplementary angles means. Not sure?...
