You are a robotic spider tangled up in an angular web. Use your knowledge of angle relationships to collect flies and teleport through wormholes to rescue your spider family!

This resource is an online glossary to find the meaning of math terms. Students can also use the online glossary to find words that are related to the word typed in the search box. For example: Type in "transversal" and 11 other terms will come up. Click on one of those terms and its meaning is displayed.

Students are asked use knowledge of angle relationships to write and solve an equation to determine an unknown angle measure.

Students are asked to write and solve equations to determine unknown angle measures in supplementary angle relationships.

Students are asked to write and solve equations to determine unknown angle measures in supplementary and complementary angle pairs.

Students are asked to use knowledge of angle relationships to write and solve equations to determine unknown angle measures.

• Solving problems relating to using the measures of the interior angles of polygons.
• Solving problems relating to using the measures of the exterior angles of polygons.

This lesson allows students to discover complementary and supplementary angles on their own. Students will measure the degrees for sets of angles. They will then use their knowledge of straight, right, obtuse, and acute angles to make connections to complementary, supplementary, adjacent, and vertical angles. This lesson will complement all different learning styles because it provides kinesthetic, auditory, and visual learning.

This lesson uses a paper cutting activity to teach vertical angles. The lesson provides examples in which students must solve equations to find missing measures.

Students, through a hands-on-activity and guided practice, will explore parallel lines intersected by a transversal and the measurements and relationships of the 8 angles created. They will solve for missing measurements when given a single angle's measurement. They will also use the relationships between angles to set up equations and solve for a variable.

Explore complementary and supplementary angles around the playground with Jacob in this interactive tutorial.

This is Part 1 in a two-part series. Click HERE to open Playground Angles: Part 2.

Help Jacob write and solve equations to find missing angle measures based on the relationship between angles that sum to 90 degrees and 180 degrees in this playground-themed, interactive tutorial.

This is Part 2 in a two-part series. Click HERE to open Playground Angles: Part 1.

The video will use algebra to find the measure of two angles whose sum equals 90 degrees, better known as complementary angles.

Watch as we use algebra to find the measure of two complementary angles. 

Watch as we use algebra to find the measure of supplementary angles, whose sum is 180 degrees.

This video uses knowledge of vertical angles to solve for the variable and the angle measures.

This video uses facts about supplementary and adjacent angles to introduce vertical angles.

This video demonstrates solving a word problem involving angle measures.

The video will demonstrate the difference between supplementary angles and complementary angles, by using the given measurements of angles.

This 5 minute video gives the proof that vertical angles are equal.

This resource will allow students to have a good understanding about vertical, adjacent and linear pairs of angles.
