WebPerimeter of a triangle, P = (a + b + c); where 'a', 'b', and 'c' are the 3 sides of the triangle. How many Types of Triangles are there in Maths? There are six types of triangles categorized on the basis of sides and angles as listed below: Scalene triangle Isosceles triangle Equilateral triangle Acute triangle Obtuse triangle WebJun 29, 2015 · In a triangle, Sum of all three angles is equal to 180°. Therefore A + B + C = 180° ------------------ (1) and given that, 2A = 3B = 6C ⇒ A = 3C, B = 2C From eqn (1), A + B +C = 180° ⇒ 3C + 2C +C = 180° ⇒ 6C = 180° ⇒ C = 180/6 = 30° Therefore A= 3C = 3×30 = 90° and B = 2C = 2×30 = 60° Advertisement Still have questions?
