The document discusses how to classify triangles based on their sides and angles. It defines scalene and isosceles triangles concerning side lengths, and acute, right, and obtuse triangles regarding their angles. Additionally, it includes examples of classifying specific triangles.

1. Classifying Triangles

2. Two Ways to Classify Triangles By Their Sides By Their Angles 03/25/11 Geometry

3. Classifying Triangles By Their Sides Scalene Isosceles 03/25/11 Geometry

4. Scalene Triangles No sides are the same length 03/25/11 Geometry

5. Isosceles Triangles At least two sides are the same length 03/25/11 Geometry
