Classifying triangles according to side length and angle measurement

Acute with angles at 89 or smaller, Right with angles at 90 exact, and obtuse with angles with 91 and above

Classifying Angles 

Classifying Triangles by Angles

Classifying Triangles By Sides

Example:  Classifying a TriangleClassify the triangle by its side lengths.The triangle has no sides of equal length. So, it is a scalene triangle.Example:  Classifying a TriangleClassify the triangle by its angles and by its side lengths.The triangle has one right angle and two sides of equal length. So, it is a right isosceles triangle.

Remember that the sum of the angle measures in the triangle is 180o. This is true for all triangles.
