1. Classifying Triangles Math 7 Ms. Conway Math 7 Ms. Conway

2. Two Ways to Classify Triangles  By their Sides  By their Angles  By their Sides  By their Angles

3. Classifying Triangles by their Sides  Scalene Triangles  Isosceles Triangles  Equilateral Triangles  Scalene Triangles  Isosceles Triangles  Equilateral Triangles

4. Scalene Triangles  No sides are the same length

5. Isosceles Triangles  Two sides are the same length

6. Equilateral Triangles  All 3 sides are the same length

7. Classifying Triangles by their Angles  Acute Triangles  Right Triangles  Obtuse Triangles  Acute Triangles  Right Triangles  Obtuse Triangles

8. Acute Triangle  Three acute angles (0 o < angle < 90 o )

9. Right Triangle  One right angle (90 o )

10. Obtuse Triangles  One obtuse angle (90 o < angle < 180 o )

11. Classify this Triangle based on its sides and angles  Right Scalene

12. Classify this Triangle based on its sides and angles  Obtuse Isosceles

13. Classify this Triangle based on its sides and angles  Right Isosceles

14. Classify this Triangle baesd on its sides and angles  Acute Scalene

15. Classify this Triangle based on its sides and angles  Obtuse Scalene

16. Classify this Triangle based on its sides and angles  Acute Isosceles

17. Challenge!!! Classify this Triangle  Equilateral

18. Great Job!
