The Triangle Sum Theorem Interior Angles
The Triangle Sum Theorem states the sum of the interior angles of a triangle equals 180 degrees. An interior angle is the angle contained by two sides of the triangle that meet at one vertex. The measure of each angle in a triangle can be determined by using the theorem and solving for x.

Concepts:
Triangle Sum Theorem: The sum of all three interior angles of a triangle is 180 degrees. Interior Angle: An angle formed by two sides of a triangle that meet at one vertex. Vertex: The point at which two sides of a triangle intersect.

Fun facts:
The Triangle Sum Theorem was discovered by the Greek mathematician Euclid in about 300BC! The Triangle Sum Theorem works for any type of triangle, including equilateral, isosceles, and scalene triangles. In a right triangle, the sum of the two smaller angles always adds up to 90 degrees!
