If two angles are complementary, that means that they add up to 90 degrees. This is very useful knowledge if you have a figure with complementary angles and you know the measurement of one of those angles. In this tutorial, see how to use what you know about complementary angles to find a missing angle measurement!
If angles combine to form a straight angle, then those angles are called supplementary. In this tutorial, you'll see how to use your knowledge of supplementary angles to set up an equation and solve for a missing angle measurement. Take a look!
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!
