Zach is a former math teacher with a Master's degree in education and a Bachelor's degree in mathematics, and is currently pursuing his PhD. Triangle height, also referred to as its altitude , can be solved using a simple formula using the length of the base and the area. Thus, the height or altitude of a triangle h is equal to 2 times the area A divided by the length of base b. The first step is to find the perimeter of the triangle p , which can be found by adding all three side lengths. Then, using the perimeter, solve for the semiperimeter s , which is equal to half the perimeter. Thus, the area A of a triangle is equal to the square root of s times s minus a times s minus b times s minus c. Then, to solve for height, use the area and the base with the formula above.

For a right triangle , there is a simple formula to solve the height, which is derived from the AA theorem and triangle similarity. However, it does require that the lengths of the three sides are known. Plug the values into the Pythagorean Theorem and solve for b 2. Plug a and c into the equation, squaring both of them. How do you find the height of a triangle given angles? Edit this Article. No account yet? Note that the variables used are in reference to the triangle shown in the calculator above.

If you are looking for an easy tool to calculate the height in any triangle , you're in the right place — this triangle height calculator is the tool for you.

The circumcenter of the triangle does not necessarily have to be within the triangle. This article was co-authored by David Jia. What is the shortest height of the 3 4 5 triangle? Plan your dream garden effortlessly now! I found the simple formula here. Plug the values into the Pythagorean Theorem and solve for b 2. So, the length of b and the height h of the equilateral triangle is equal to the square root of the square of the hypotenuse c divided by 2 plus the square of the hypotenuse. This was extremely helpful, thank you so much. Then we can derive the height h h h starting from Pythagoras's equation:. What is more, the calculator showed us all triangle angles, the area, and the perimeter.
