Triangles are three-sided objects. All three sides are made up of angles. An angle is made up of two rays. These rays meet at a common endpoint.

Look at the following triangle.
When you look at the following triangle what is your first thought? You have seen this shape more than once.
If you have ever been to a racetrack, the tiny flags throughout the course have this shape. You may have the same kind of flag on the back of your bike! The local high school or college banners you wave at football games have this shape, too.
You probably are not thinking about the size of each angle. Unless you are measuring something that requires the knowledge of finding the size of the angles, you may not pay attention to the angles at all.
