A radius of a regular triangle is 12 . find the length of one side of the triangle?
Divide the length of a side of one triangle by the length of the corresponding side of the other triangle.

An isosceles triangle has 2 equal sides and 1 side different in length
One side is not enough. For a right triangle the third side can be calculated by Pythagoras' Theorem if you know the length of any two sides.
The minimum third side length of a triangle having one side of 11 and another side of 5 is 6.
-- Area of a triangle = 1/2 of (length of the base times height) -- Perimeter of a triangle = (length of one side) + (length of another side) + (length of last side)
Perimeter of a triangle = (length of side #1) + (length of side #2) + (length of side #3)
A triangle with 2 equal side lengths is called an isosceles triangle.
Only if the triangle is degenerate.
-- Find the length of one side. -- Find the length of another side. -- Find the length of the remaining side. -- Add the three numbers. -- Their sum is the perimeter of the scalene triangle.
To get the area of an equilateral triangle, you just need to know the length of one side. Multiply the length of one side by the square root of three and then divide the product by four, and you will get the area of the triangle.
