Angles can be grouped based on how big they are, especially as complementary or supplementary angles.
What are they? Two angles are called complementary if they add up to 90 degrees.
Example: If one angle is 30 degrees, the other one needs to be 60 degrees because 30 degrees + 60 degrees = 90 degrees.
Fun fact: In any right triangle, the two angles that are not right angles are always complementary. This is important because the total of all three angles in a triangle adds up to 180 degrees.
What are they? Two angles are supplementary if they add up to 180 degrees.
Example: If one angle is 110 degrees, its supplementary angle would be 70 degrees because 110 degrees + 70 degrees = 180 degrees.
Fun fact: Supplementary angles often appear in pairs along a straight line. They share one side and a point (called a vertex). This is vital for understanding straight lines and how they work.
Knowing the difference between complementary and supplementary angles helps you solve different problems in geometry. It also helps you find missing angles. Plus, understanding these angles can be useful in real life, like in building designs and architecture!
