How do you find the interior angles of a triangle if only one angle is given?

Question

AL2006 · Answer

You can't, if you only know one angle. That's not enough information to find the other two. If this is a homework problem, then I'm sure you're given some more info.

AL2006 · Answer

You cannot find the other two angles of a triangle if you only know one angle because the sum of the angles in a triangle is always 180 degrees. To find the other angles, you need more information, such as another angle or the lengths of the sides. The relationship can be expressed as B + C = 180 - A, where A is the known angle.
