Trying to find a missing interior angle measurement in a triangle? Already know the other two interior angle measurements? Then you're set! Just remember that the interior angles of a triangle ALWAYS add up to 180 degrees. This tutorial shows you how to put this knowledge into an equation and solve to find that missing measurement!
Doing math with paper and pencil can come in real handy, so make sure you're comfortable adding decimals by hand. After all, you don't want the calculator to be a crutch!
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!
Plugging variables into an expression is essential for solving many algebra problems. See how to plug in variable values by watching this tutorial.
Trying to find a missing interior angle measurement in a triangle? See if you're working with a special type of triangle such as an equilateral or isosceles triangle. If you are, that knowledge can help you. In this tutorial, see how identifying your triangle first can be very helpful in solving for that missing measurement. Take a look!
Looking for the measurements of the interior angles of a given triangle? The Triangle Sum theorem might help. This theorem states that the interior angles of a triangle ALWAYS add up to 180 degrees! This tutorial shows you how to use that information to find those interior angle measurements.
