Question

Classifying triangles according to side length and angle measurement

Answer 1

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.

Answer 2

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