You have to use Pythagorean theory, which is a^2 + b^2 = c^2. So a is the base of the triangle, b is the leg of the triangle, and c is the hypotenuse. (This only works for a a triangle with a 90 degree angle)
Using Pythagoras' theorem the third side works out as 4 units in length.
If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.
-- Measure or calculate the length of one side. -- Measure or calculate the length of another side. -- Measure or calculate the length of the only remaining side. -- Add the three numbers. The sum is the perimeter of the triangle.
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
The minimum third side length of a triangle having one side of 11 and another side of 5 is 6.
If the third side is the hypotenuse of a right triangle, it is 10.0
The length of the third side of this triangle must be greater than 1 foot and less than 5 feet, and the third side would be either 2 feet or 3 feet if it were an isosceles triangle.
An isosceles triangle.
The method depends on the information that you have.
To find the perimeter of a triangle, you need to add the lengths of all three sides. If two sides of the triangle are 6 and 5 units long, you still need to know the length of the third side to find the perimeter. Without the length of the third side, it is not possible to calculate the perimeter of the triangle.
The third side would be either 5 or 8,as an isosceles triangle has 2 equal sides.
You need the measures of two sides and for the triangle to be a right triangle to figure out the third side.
