What are Supplementary Angles?
Note:
Knowing about supplementary angles can be very useful in solving for missing angle measurements. This tutorial introduces you to supplementary angles and shows you how to use them to solve for a missing angle measurement. Take a look!
Background Tutorials
-
Distinguish between undefined terms, definitions, postulates, conjectures, and theorems
-
What is a Point?
A point is a fundamental building block of math. Without points, you couldn't make lines, planes, angles, or polygons. That also means that graphing would be impossible. Needless to say, learning about points is very important! That makes this tutorial a must see!

-
Verify theorems about the relationships in triangles, including proof of the pythagorean theorem, the sum of interior angles, base angles of isosceles triangles, midsegments, and medians, and apply these relationships to solve problems
-
What is an Angle?
Angles are a fundamental building block for creating all sorts of shapes! In this tutorial, learn about how an angle is formed, how to name an angle, and how an angle is measured. Take a look!
-
What are Acute, Obtuse, Right, and Straight Angles?
Did you know that there are different kinds of angles? Knowing how to identify these angles is an important part of solving many problems involving angles. Check out this tutorial and learn about the different kinds of angles!
-
Further Exploration
-
communicate mathematical ideas, reasoning, and their implications using multiple representations, including symbols, diagrams, graphs, and language as appropriate
-
What are Complementary Angles?
Do complementary angles always have something nice to say? Maybe. One thing complementary angles always do is add up to 90 degrees. In this tutorial, learn about complementary angles and see how to use this knowledge to solve a problem involving these special types of angles!
