How to find the length of a triangle. This calculator calculates for the length of one side of a right triangle given the length of the other two sides. The pythagorean theorem is a theorem specific to right triangles. Fill in the lengths you know in the equation. Fill in the lengths.

The 300 600 900 refers to the angle measurements in degrees of this type of special right triangle. For any right triangle the square of the length of the hypotenuse equals the sum of the squares of the lengths of the two other sides. Sides a and b are the perpendicular sides and side c is the hypothenuse. Divide the length of the shortest side of the main triangle by the hypotenuse of the main triangle.

The two new triangles you have created are similarto each other and the main triangle. In this type of right triangle the sides corresponding to the angles 300 600 900 follow a ratio of 1 32. If you know two angle measures and a side length on a triangle you can use the law of sines to find the missing parts of the triangle. The theorem states that the hypotenuse of a right triangle can be easily calculated from the lengths of the sides.

Mathematicians have no special formula for finding the perimeter of a triangle they just add up the lengths of the sides. Find the base or height of a triangle when given the other and the area. To find the area of a triangle you need to know the length of one side the base b for short and the height h. This is the pythagorean theorem used for solving for.

Thus in this type of triangle if the length of one side and the sides corresponding angle is known the length of the other sides can be determined using the above ratio. Since we know 1 side and 1 angle of this triangle we will use sohcahtoa. Enter the length of any two sides and leave the side to be calculated blank. Set up your equation so that a 2 b 2 c 2.

In this case you need to know either two angles and the side in between them angle side angle or asa or two angles and a consecutive side angle angle side or aas. Find missing length when given area of a triangle. The hypotenuse is the longest side of a right triangle. How to find the length of the side of a triangle if you know the other two sides draw the triangle.

Set up your equation. Note that the height forms a right angle with the base. Set up an equation using the sine cosine or tangent ratio since we want to know the length of the hypotenuse and we already know the side opposite of the 530 angle we are dealing with sine. Find the base or height of a triangle when given the other and the area.

Multiply the result by the length of the remaining side to get the length of the altitude.
