Triangles can be classified by their angles or by their sides Sides Type of Triangle All three sides have different lengths Scalene Triangle Only two sides are congruent (equal length) Isosceles Triangle All three sides are congruent (equal length) Equilateral Triangle Angles Type of Triangle one 90 degree angle and two angles less than 90 degrees Right Triangle All three angles are less than 90 degrees Acute Triangle One angle greater than 90 degrees and two angles Obtuse Triangle less than 90 degrees. If you are given a triangle, you need to be able to classify them without notes. 1
