To find the square of the hypotenuse, c, you must know the values of the other two sides (a and b). Square each of the two sides and add them together. This will be the value of the hypotenuse squared.

(a2 + b2) = c2

To find the value of the hypotenuse, determine the square root of both sides of the equation.

√(a2 + b2) = √c2 = c

How can you find the base of a right triangle when you have the height and hypotenuse?

The square of the length of the base plus the square of the length of the height will equal the square of the length of the hypotenuse of your right triangle, per Pythagoras. Square the hypotenuse, subtract the square of the height, and then find the positive square root of that and you'll have the base of your right triangle.


How can you find the height of a right triangle when you have the base and hypotenuse?

-- Square the hypotenuse. (Multiply it by itself.)-- Square the base. (Multiply it by itself.)-- Subtract the square of the base from the square of the hypotenuse.-- Take the square-root of the difference. It's the height of the triangle.


How do you find the hypotenuse of triangle?

If it has no right angles, it is not a right triangle and therefore you cannot name a hypotenuse of that triangle. Which implies you cannot find that side's measure.


How do you find the hypotenuse of a triangle that has no right angles?

If it has no right angles, it is not a right triangle and therefore you cannot name a hypotenuse of that triangle. Which implies you cannot find that side's measure.


Find hypotenuse of right triangle of 300Cm and 400Cm?

The hypotenuse of right triangle of 300Cm and 400Cm is: 500 cm


Find the hypotenuse of a right triangle if one leg is 8 and the other leg is 15?

The hypotenuse is the square root of (82 +152) = 17.


What is hypotenuse in an isosceles triangle?

Only a right triangle has a hypotenuse. An isosceles triangle can be a right triangle but it doesn't have to be. If it's not, then it doesn't have a hypotenuse.


How do you find the hypotenuse to a triangle?

First of all, you have to make sure that it's a RIGHT triangle. That means that one of the angles in the triangle is 90 degrees. If not, then it's not a right triangle, and it doesn't have a hypotenuse. If it IS a right triangle, then the longest side is the hypotenuse.


How do you calculate hypoteneous of a right angled triangle?

The hypotenuse is the longest side of the right triangle. To calculate the hypotenuse of a right triangle, you would square the sides, add them up, and find the square root of the sum. When you find the square root of the sum, that will be the hypotenuse of your right triangle. For instance, let's say you are given a triangle. We'll call it Triangle ABC. In the triangle, you have three sides, Side A, Side B, and Side C. Sides A and B will represent the two known legs, also the shortest legs. Side C will represent the hypotenuse, the side we're trying to find. We know that Side A is 5km and that Side B is 12km. Now we just have to calculate the hypotenuse of the right triangle. To do that you would square both sides and add them, first. Like this: (5 x 5) + (12 x 12) which is the same as saying 25 + 144. Now you find the sum, which is 169. Now, there is one last step, finding the square root of the sum. Our square root would be 13, because we know that 13 x 13=169. So now you have found the missing side, the hypotenuse of the right triangle (Side C) which is 13km. And that's how you find the hypotenuse of a right triangle. Hope I could help!


How do you find the hypotenuse of a non right triangle?

By definition, the hypotenuse is the side opposite the right angle in a right angled triangle. Therefore, a hypotenuse does not exist as one of the three sides in a non-right angled triangle.
