Supplementary and Complementary Angle Pairs

Complement the class by identifying pairs of angles. With a vocabulary lesson, pupils learn the names and definitions of special angle pairs including adjacent, vertical, complementary, supplementary, and linear pairs. Using the...

You're such a great resource, said the complementary angle. A short video in the Socratica Geometry playlist describes complementary, supplementary, and vertical angles. It also shows how to calculate the other angle in a supplementary...

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...

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.

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.

Soccer is all about angles. Young mathematicians use an interactive to correctly position the path of a soccer ball so that it reaches the goal. They consider complementary angles when answering a set of challenge questions.

Here's an interactive that complements your lesson plans. Users of the resource adjust one of the angles in a complementary set to see how it affects the other. A set of challenge questions assesses understanding.

One quadrant just isn't enough. Pupils learn to plot points in the four quadrants of a coordinate plane using an interactive. A set of challenge questions tests their understanding of the skill.

Classify this resource into the "Use" pile. Scholars use an interactive coordinate plane to plot polygons given coordinates for the vertices. They use properties to classify each polygon and answer a few challenge questions regarding the...

Students are introduced to the "Walk the Line" challenge question. They are asked to write journal responses to the question and brainstorm what information they need to answer the question. Ideas are shared with the class (or in pairs...
