The perimeter of any triangle is the sum of its 3 sides.
Use two sides and Pythagoras's theorem to work out the third side. Then simply add the three sides.
-- Measure or calculate the length of each of its 3 sides. -- Add the lengths of its 3 sides. -- The sum is the perimeter of the triangle.
With sides of 5 and 12, you can make a triangle with any perimeter you want between 24 and 34. If you call them "legs" because they are the sides of a right triangle, then the hypotenuse is 13, and the perimeter is 30.
To find the perimeter of this right angled triangle you need the missing side first Use Pythagoras theorem 10 2 - 8 2 = 36 missing side = sqroot 36 = 6 perimeter =sum all sides = 10+8+6 = 24inches
The perimeter of any triangle is the sum of its 3 sides.
Surely you know how to find the third side of a right triangle, when you know the lengths of the other two. Find it, and then add up the lengths of the three sides to get the perimeter.

The perimeter of a triangle is simply the sum of the lengths of its three sides. Knowing that it is right angles (or not) is rarely of help.

13 cm and it is an isosceles triangle 55 - 2*21 = 13
