Triangle Angle Sum Theorem Worksheet
The triangle is one of the most fundamental shapes in geometry, and many mathematical principles are built on its properties. Among these, the Triangle Sum Theorem stands as a cornerstone, establishing that the sum of the interior angles of any triangle is always equal to 180 degrees. This theorem is not only a basic fact to memorize but also an essential building block that enables more advanced geometric reasoning.
