Classification of Triangles According to anglesIf one angle of a triangle is a right angle (90°), then it is called a Right triangle. Note that the other two angles are acute.If all the angles of a triangle are acute (less than 90°), then it is called an acute angled triangle.If one angle of a triangle is obtuse (greater than 90°), then it is called an obtuse triangle. Note that the other two angles are acute.According to sides:If any two sides of a triangle are equal, then it is called an Isosceles Triangle. In ABC, AB = AC ABC is isosceles.If all the three sides of a triangle are equal, then it is an Equilateral Triangle. In ABC, AB = BC = CA ABC is equilateral.If no two sides of a triangle are equal, then it is called a Scalene Triangle. In ABC, AB BC CA. ABC is scalene.
