Triangles can be classified either according to their sides or according to their angles. All of each may be of different or the same sizes; any two sides or angles may be of the same size; there may be one distinctive angle. 

Equilateral triangle: A triangle with all three sides equal in measure. 

Isosceles triangle: A triangle in which at least two sides have equal measure 

Scalene triangle: A triangle with all three sides of different measures

Right triangle: A triangle that has a right angle in its interior 

Acute triangle: A triangle having all acute angles (less than 90°) in its interior

Equiangular triangle: A triangle having all angles of equal measure
