For a complete lesson on complementary and supplementary angles, go to http://www.MathHelp.com – 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn the definition of complementary and supplementary angles, as well as how to find the measures of the complement and supplement of a given angle. Students are also asked to solve word problems in the following form: “If the ratio of an angle to its complement is 2:3, find the measure of each angle.”

Thanks to all of you who support me on Patreon. You da real mvps! per month helps!! 🙂 https://www.patreon.com/patrickjmt !! Complementary and Supplementary Angles – Example 1. In this video, I discuss what it means for angles to be complementary and supplementary and do a few problems where I find complements and supplements for different angles.

What are complementary angles

Learn how to define angle relationships. Knowledge of the relationships between angles can help in determining the value of a given angle. The various angle relationships include: vertical angles, adjacent angles, complementary angles, supplementary angles, linear pairs, etc.

Vertical angles are two angles opposite each other at the point of intersection of two lines. Vertial angles are equal. Adjacent angles are angles sharing a common side. Complementary angles are two angles whose sum is 90 degrees. Supplementary angles are two angles whose sum is 180 degrees. Linear pair are two adjacent angles whose sum is 180 degrees.

Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large–from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine (“It’s good for you!”), it’s at the core of everything that exists–including you. Having said all that, some of the specific topics we’ll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That’s a lot. To summarize: it’s difficult to imagine any area of math that is more widely used than geometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We’ve also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
