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.

This isosceles triangle height calculator will calculate for you the two heights of an isosceles triangle. It will also tell you whether you have a valid isosceles triangle. Read on to learn about:. An isosceles triangle is a triangle where two sides are of equal length. You can also argue that a triangle where all three sides are equal an equilateral triangle is a special case of an isosceles triangle. Isosceles triangles date back to ancient Egypt, where it was used for decoration and in their architecture — even the face of a pyramid is an isosceles triangle. We can derive the formula for the height of an isosceles triangle as measured from the base to the vertex between the two equal legs from Pythagoras's Theorem if we look for a right-angle triangle inside the isosceles triangle. You can form one if you only consider half of an isosceles triangle, cutting at the midpoint of the base side b b b in the figure above the calculator. Then we can derive the height h h h starting from Pythagoras's equation:. Using this isosceles triangle height calculator is really straightforward. Here are the steps to follow:. Note that if you want to calculate the lengths in different units, you can change the unit before entering a value. Changing the unit after entering a value, the calculator is also a length unit converter.

The altitude h of a right triangle is equal to a times bdivided by c. How to use the isosceles triangle height calculator Using this isosceles triangle height calculator is really straightforward.

To calculate the area of a triangle you need to know its height.

Please provide 2 values below to calculate the other values of a right triangle. Right triangles, and the relationships between their sides and angles, are the basis of trigonometry. The sides of a right triangle are commonly referred to with the variables a, b, and c, where c is the hypotenuse and a and b are the lengths of the shorter sides. The altitude divides the original triangle into two smaller, similar triangles that are also similar to the original triangle. If all three sides of a right triangle have lengths that are integers, it is known as a Pythagorean triangle.

Please provide 3 values including at least one side to the following 6 fields, and click the "Calculate" button. A triangle is a polygon that has three vertices. A vertex is a point where two or more curves, lines, or edges meet; in the case of a triangle, the three vertices are joined by three line segments called edges.

Question or Feedback. If you know the base and area of the triangle, you can divide the base by 2, then divide that by the area to find the height. How to find the height of a triangle — formulas How to find the height of an equilateral triangle How to find the height of an isosceles triangle How to find the altitude of a right triangle How to find the altitude of the triangle with this triangle height calculator? Article Summary. Tick marks on the edge of a triangle are a common notation that reflects the length of the side, where the same number of ticks means equal length. Then, using the perimeter, solve for the semiperimeter s , which is equal to half the perimeter. If you cut an equilateral triangle in half, you will end up with two congruent right triangles. Using this isosceles triangle height calculator is really straightforward. Embed Share via. The height you solve for with the steps above would be the height from the base b to the vertex opposite of base b. This article has been viewed 2,, times. The resulting value will be the height of your triangle! If your shape is a special triangle type, scroll down to find the triangle height formulas.

The triangle calculator finds all triangle measurements — side lengths, triangle angles, area, perimeter, semiperimeter, heights, medians, inradius, and circumradius. The triangle calculator is an online triangle solver allowing you to find all triangle measurements based on three known measurements quickly. The calculator takes the lengths of the sides of a triangle and triangle angles as inputs and calculates the following measurements:.

Learn why people trust wikiHow. Divide the result by 2. The altitude divides the original triangle into two smaller, similar triangles that are also similar to the original triangle. In other languages Italiano: Trovare l'Altezza di un Triangolo. The circumcenter of the triangle does not necessarily have to be within the triangle. You'll instantly receive a value for the height of the triangle , as measured from the base to the vertex h b. This is because there are infinitely many triangles with these angles, and the lengths of the altitudes in each of these triangles are different! Furthermore, triangles tend to be described based on the length of their sides, as well as their internal angles. The "base" refers to any side of the triangle where the height is represented by the length of the line segment drawn from the vertex opposite the base, to a point on the base that forms a perpendicular.
