Two Ways to Classify Triangles  By Their Sides  By Their Angles Geometry

Classifying Triangles By Their Sides  Scalene  Isosceles Geometry

Scalene Triangles  No sides are the same length Geometry

Isosceles Triangles  At least two sides are the same length Geometry

Classifying Triangles By Their Angles  Acute  Right  Obtuse Geometry

Acute Triangles  Acute triangles have three acute angles Geometry

Right Triangles  Right triangles have one right angle Geometry

Obtuse Triangles  Obtuse triangles have one obtuse angle Geometry
