Solution: Since all three sides are equal in length, this is an equilateral triangle. Find the perimeter of a triangle if each side is 10 cm? Perimeter of a scalene triangle = (a + b + c) = 6 +5 + 3 = 14Ģ. Solution: Since all the three sides are unequal, it is a scalene triangle. Find the perimeter of a triangle if the sides are 6 cm, 5 cm, and 3 cm? Now, we can write the perimeter of a right triangle as Hence, using the Pythagoras theorem, we get Since this is a right-angled triangle, we can use the Pythagoras theorem to find the length of any side which is not known. Where a, b, and c = the lengths of the sides Perimeter of a right-angled triangle = (a + b + c) The formula to calculate the perimeter of a right-angled triangle is: ![]() We can calculate the perimeter of a right-triangle by adding the length of its sides. Where, a = length of any of the sides of the equilateral triangle.Ī right-angled triangle has one of the angles as 90º. The perimeter of an equilateral triangle = (a + a + a) = (3 × a) We can calculate the perimeter of an equilateral triangle by the formula given below: If a triangle has all the sides of equal measure, it is an equilateral triangle. The Perimeter of the Equilateral Triangle The formula for the perimeter of an isosceles triangle = (l + l + b) = (2l + b) We can calculate the perimeter of an isosceles triangle by finding the sum of its sides. ![]() The formula for the perimeter of a scalene triangle = (a + b + c), where a, b, and c are the lengths of the sides of the triangle.Ī triangle that has two sides of the same length and one side of a different length is called an isosceles triangle. ![]() We can calculate the perimeter of a scalene triangle by calculating the sum of all the sides. Now we will understand this formula for the different types of triangles.Ī scalene triangle has three sides measuring different lengths. So, the perimeter of triangle formula = sum of the lengths of three sides of the triangle. We can calculate the perimeter of a triangle by adding the lengths of the three given sides. The total length of any two-dimensional figure is called its perimeter. The perimeter of a triangle represents the sum of all three sides of the triangle. ![]()
