  1. Classifying Triangles Classifying means naming. You will learn ways to name triangles.

  2. Two Ways to Classify Triangles • By Their Sides • By Their Angles Side Side Side Angle

  3. Classifying Triangles By Their Sides • Scalene • Isosceles • Equilateral

  4. Scalene Triangles • No sides are the same length 10 4 12

  5. Isosceles Triangles • At least two sides are the same length 8 8 5

  6. Equilateral Triangles • all sides are the same length 9 9 9

  7. Classifying Triangles By Their Angles • Acute • Right • Obtuse

  8. Acute Triangles • Acute triangles have three acute angles • Smaller than 90 degrees

  9. Right Triangles • Right triangles have one right angle 90 degree angle

  10. Obtuse Triangles • Obtuse triangles have one obtuse angle Bigger then 90 degrees
