Right Triangle Calculator

How does the right-angle triangle calculator work?

The right-angle triangle calculator is a tool used to solve for different characteristics of right-angle triangles, these characteristics include finding the hypotenuse, determining the area, and calculating the perimeter of right-angle triangles. After the known values have been entered into the calculator, click on "calculate".

Why use the right-angle triangle calculator

The hypotenuse, one of the most significant measurements in human history, the hypotenuse is used for solving many problems! A major use for the hypotenuse is for marine navigation, seamen often use it to triangulate their location. The area of right-angle triangles can be important for those who want to find the living area of triangular spaces! Perimeter has also been used to set up land in triangular forms, now you will know the length of fence needed to buy! What will you use the right-angle triangle calculator for?

A brief history of triangulation?

Triangulation in the present day is used for many purposes, namely, navigation, metrology, astrometry, model rocketry, and in the military, to accurately aim and fire weapons. In the 6th century BC, around 250 years before the establishment of the Ptolemaic dynasty, a Greek philosopher named Thales was recorded as using similar triangles to estimate the height of the pyramids of ancient Egypt.

Input fields explained

Before we begin it may help to understand each input field:

  • Side A length:

    Enter the length of the side labeled side A in the right-angle triangle calculator.
  • Side B length:

    Enter the length of the side labeled side B in the right-angle triangle calculator.
  • Property to solve:

    Select the characteristic for which you wish to calculate (Hypotenuse, area, perimeter).

Understanding the results

The right-angle triangle calculator uses the Pythagorean theorem to solve for the "hypotenuse" if that is the characteristic that has been selected, otherwise, the right-angle triangle calculator will provide "perimeter" as the answer if that is the selected problem, if "area" is chosen, the right-angle triangle calculator will calculate the area of the triangle.
