What is the Right Triangle?

A right triangle has one angle measuring precisely 90 degrees, known as the right angle. The other two angles are acute, meaning each is less than 90 degrees. The side opposite the right angle is called the hypotenuse, and the other two sides are the legs of the triangle.

In a right triangle, the Pythagorean theorem is a fundamental principle that relates the lengths of the sides. The theorem states:

a2 + b2 = c2

Where:

• a and b are the lengths of the legs,
• c is the length of the hypotenuse.

How to Use the Right Triangle Calculator?

Using our Right Triangle Calculator involves a few straightforward steps:

1. Input Known Values: Enter the values of the sides or angles that you already know. You may be given the lengths of the two legs, the hypotenuse, or one of the angles.
2. Select the Calculation Type: Choose what you need to calculate:

• Length of a Missing Side: Calculate the size of an unknown side given the lengths of the other two sides.
• Angle Measurement: Determine the measure of an unknown angle given the lengths of the sides.

3. Perform the Calculation: After entering the known values and selecting the calculation type, click the “Calculate” button. The calculator will process the data and provide the results.

The result will display the length of the missing side, the measure of the missing angle, or any other relevant properties.

Example;

With our Right Triangle Calculator, you can efficiently solve right triangle problems, perform accurate calculations, and better understand geometric relationships in right triangles. Let’s use an example to illustrate how the Right Triangle Calculator works.

Problem: Calculate the length of the hypotenuse of a right triangle with legs measuring 6 cm and 8 cm.

Solution

• Use the Pythagorean theorem: a2 + b2 = c2

.

• Substitute the known values into the formula: 

a2 + b2 = c2

62 + 82 = c2

100= c2

100= c

c= 10 cm

Result: The length of the hypotenuse is 10 cm.
