Two Ways to Classify Triangles By their Sides By their Angles By their Sides By their Angles
Classifying Triangles by their Sides Scalene Triangles Isosceles Triangles Equilateral Triangles Scalene Triangles Isosceles Triangles Equilateral Triangles
Scalene Triangles No sides are the same length
Isosceles Triangles Two sides are the same length
Equilateral Triangles All 3 sides are the same length
Classifying Triangles by their Angles Acute Triangles Right Triangles Obtuse Triangles Acute Triangles Right Triangles Obtuse Triangles
Acute Triangle Three acute angles (0 o < angle < 90 o )
Right Triangle One right angle (90 o )
Obtuse Triangles One obtuse angle (90 o < angle < 180 o )
Classify this Triangle based on its sides and angles Right Scalene
Classify this Triangle based on its sides and angles Obtuse Isosceles
Classify this Triangle based on its sides and angles Right Isosceles
Classify this Triangle baesd on its sides and angles Acute Scalene

Classifying Triangles. What do we remember about classifying angles? What are the different types of angles? Acute, right, obtuse, and straight.
HOW MANY SIDES ARE THERE, AND WHAT IS THEIR ANGLE?
Classifying Triangles Students will classify triangles using the lengths of the sides and the angles. S. Calahan October 2010.
