Triangle Classification Overview
- Triangles can be classified into three types based on their angle measures: acute, obtuse, and right.
- Acute triangle: All angles are less than 90 degrees.
- Obtuse triangle: One angle is greater than 90 degrees.
- Right triangle: One angle is exactly 90 degrees.
