Sides of a Triangle

Students learn to classify triangles as scalene (all sides have different lengths), isosceles (at least two sides have the same length), or equilateral (all sides have the same length). Students also learn that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
