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
