Give this advanced 30 60 90 triangle calculator a try to figure out all the parameters related to this type of triangle. The tool also provides you with step-by-step calculations by using different formulas, thereby ensuring accuracy at its utmost choice.

Let’s move down and learn how to solve 30 60 90 triangles!

## Definition:

**“A 30 60 90 triangle is a special type in which the measure of three angles are in the ratio 1:2:3, respectively”**

As you see, there is an angle of 90 degrees in this geometrical figure, so we can assume it to be a right triangle as well.

## How To Solve a 30 60 90 Triangle?

Well, it’s quite simple! Our 30-60-90 triangle calculator considers the following equations to determine all the parameters accurately:

### Sides:

The lengths of all three sides in this triangle are not the same. Among these are:

- Longest side of a hypotenuse
- The other two sides as the normal ones that we can also determine with this calculator

### Mathematically:

If the measure of the smallest side is a, then we have:

- b = a√3
- c = 2a

If the measure of the longer side rather than the hypotenuse is given with the perimeter, we have:

- a = b√3/3
- c = 2b√3/3

At last, if you only have the measure of the hypotenuse, then 30 60 90 triangle formula for the other two sides is as follows:

- a = c/2
- b = c√3/2

## Perimeter:

- P = a × (√3 + 3)

### Area:

- A = ab/2
