Let consider the right triangle ABC with hypotenuse AB and heigth AC then base is BC

Pythagorean theorem states that AB2=AC2+BC2 so BC2=AB2-AC2 then BC=sqrt(AB2-AC2)

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 base and height of a triangle if you only have the hypotenuse?

I'm pretty sure that only works if it is an isosceles right triangle. In that case, use the Pythagorean theorem to calculate the base and height knowing only the hypotenuse. A2 + B2 = C2. A=B= height= base. C= hypotenuse


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.


What is the area of a right triangle and the hypotenuse is 10.6?

Area = 0.5*base*height You will need to know the base or height then use Pythagoras theorem to find the base or height.


How do you find the area of the right angle triangle given the base hypotenuse and perimeter?

It is: perimeter minus hypotenus+base = height Area = 0.5*base*height


How do you find the hight of a triangle?

If you know the base and the hypotenuse (the other line that isn't the height), the hypotenuse squared minus the base squared equals the height squared. Example: base = 5 hypotenuse = 13 a2 - b2 = c2 25 - 169 = c2 144 = c2 12 = c height is 12


How do you find the height of a fight triangle when the hypotenuse is 9?

I guess you meant a right triangle with a hypotenuse of 9 units.Long answer:If the hypotenuse is used as the base of the triangle, the height will be any value greater than 0 units and less than or equal to 41/2 units.If one of the other two sides is used as the base, then the height will be any value greater than 0 units and less than 9 units such that height = √(81 - base2).Short answer:You can't without further information about one of the other two sides.Short answer expanded:Then you can use Pythagoras to find the third side.If one if the non-hypotenuse sides is the base, then the height is the other side.Otherwise with the hypotenuse as the base, the height is given by:height = product_of_the_other_two_sides ÷ hypotenuse


How do you find the base and the height of a triangle if you have the hypotenuse?

You cannot. You need to know the length of one of the sides to find the other, or either of the acute angles.


How do you find the area of a triangle when you only know the height?

if you know the two legs of the triangle, you can use the Pythagorean theorem to find the hypotenuse as the base. Then you use the formula to find the area of the triangle: 1/2 (pi) bh.


How do you find the area of a right triangle when you have the base and hypotenuse?

Use Pythagoras' theorem: hypotenuse2-base2 = height2 and then square root this to give the actual height 1/2*base*height = area


How do you find the area and perimiter of a triangle?

To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle. To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle.
