How do find the perimeter of a triangle?

The easiest way is if you already have the lengths of all three sides of the triangle. In which case, you simply add their lengths together to acquire the perimeter. However, if you only have the lengths of two sides of a triangle, and it's a right triangle"; you can use the Pythagorean Theorem to determine the length of the third side. Note: Here are some quick definitions of terms that will be used in the following equations. A² will represent the height of the triangle. B² will represent the width of the triangle. C² will represent the hypotenuse of the triangle. The "Hypotenuse" is the longest side of a triangle. A "Right Triangle" is a triangle that has an angle measuring 90°. When using the Pythagorean Theorem; if you're attempting to find hypotenuse of a triangle; you use the formula "A² + B² = C²". That is; you square the two known sides; then add the products. Upon doing that, find the square root of the sum of both numbers, and you have the length of the hypotenuse. Upon finding the missing side's length; add the lengths of all three sides, and the resulting number will be the perimeter of the triangle. If you have the length of one side, and the hypotenuse of a right triangle; and are seeking to find the third side's length; you use the formula "C² - A² = B²" or "C² - B² = A²"; depending on which side your attempting to find the length of. Like in the previous equation, add the lengths of all three sides together to acquire the perimeter.


Does the hypotenuse of a triangle represent a third dimension?

No, the hypotenuse of a triangle does not represent a third dimension. A triangle is a 2 dimensional figure consisting of only dimensions in terms of x and y. In order to be a 3d figure it would need dimensions defined in terms of x, y, and z.


How do you find the lengths of two sides of a triangle using Pythagorean theorems?

To find the lengths of two sides of a triangle using the Pythagorean theorem, you would need to know the length of the third side. Once you have that information, you can use the theorem to calculate the lengths: a^2 + b^2 = c^2, where a and b are the two smaller sides of the triangle and c is the length of the hypotenuse. Rearrange the formula to solve for the unknown side lengths.

How do you determine the length of the 3rd leg in a right triangle if you have the length of the other two legs?

A right triangle only has two legs, the third side is called the hypotenuse . The square of the length of the hypotenuse is equal to the sum of the squares of the two legs. The square root of the difference of the square of the hypotenuse and the square of one leg is equal to the length of the other leg.

In a 30-60-90 right triangle the length of the hypotenuse is?

You need the length of a side. Try sketching different size triangles with 30/60/90 degree angles - there's an infinite number of them. The length of the hypotenuse is the shortest side / sin30 or the third side / sin60. As sin 30 is 0.5 then the hypotenuse is twice the length of the shortest side (or the third side divided by ½root3 ).


What equation do you use to find the adjacent side length of a triangle if you know the hypotenuse and the opposite side?

Third side = sqrt(hyp2 - opp2)


Can you find the length of one side with the hypotenuse and the right angle?

No. You need either another angle or the length of another side. For example, to solve a2 +b2=c2 (the formula for a right triangle, in which c is the hypotenuse) you must have values for 2 variables to solve for the third.

How do you find the third side of a triangle when two sides are known?

Use Pythagoras' theorem or trigonometry depending on what type of triangle it is. ` Only if it is a right triangle you will be able to use Pythagoras' theorem. This formula states that a^2 + b^2 = c^2 Where a and b are your two of the sides and c is the hypotenuse of the triangle. f you know the hypotenuse but not one of the other sides you can manipulate this formula.
