# ​Triangle 30 60 90 Calculator

This is a special right triangle having 30, 60, and 90 angles from all sides. In order to perform specific calculations regarding this type of triangle, you can take the support of different branches of mathematics including trigonometry.

Unit of length:

Most often we use centimeter cm or meter m for the three sides of the triangle. However, other than the sub-units of meters, you can go with yards, miles, acres, and so on for further.

These are the same for the perimeter. For the area, the units will be square centimeters, and so on.

## Formula of ​Triangle 30 60 90 Calculator

In order for a better understanding, assume that the shorter side of the triangle is “A”

Then,

• The hypotenuse will be 2A

• And the third side of the triangle will be A√3

To find the area we will use,

A² √3/2

Furthermore, the perimeter will be equal to

A(3 + √3)

Note:

To calculate the perimeter of a triangle, you can use our Perimeter Of A Triangle Calculator.

### Rules of 30 60 90 Triangle

In the special right angle, there is a side with 90 degrees and you will find a consistent relationship between the other two. It is easy to remember the relevancy among the three sides and that is:

a: a√3: 2a

You will find these values different if the angles have different values that can be 45 45 90 triangles.
