# Triangle Calculator

Triangle calculator computes the base of a triangle given the height and the area. A closed polygon that has 3 edges, 3 vertices, and 3 angles is known as a triangle. The classification of triangles is based on the measure of the sides and the angles.

## What is a Triangle Calculator?

Triangle Calculator is an online tool that helps to calculate the base of a triangle by using the area formula. In order to apply the area formula to determine the base, we need to know the height as well as the area of the triangle. To use this **triangle** **calculator**, enter values in the input box.

## How to Use the Triangle Calculator?

Please follow the below steps to find the base of the triangle using the online triangle calculator:

**Step 1:**Go to online triangle calculator.**Step 2:**Enter the values in the input box of the triangle calculator.**Step 3:**Click on the**"Calculate"**button to find the base of the triangle.**Step 4:**Click on the**"Reset"**button to clear the fields and enter new values.

## How Does Triangle Calculator Work?

There are many different types of triangles in geometry. These are categorized as follows:

**Based on side lengths**

- Equilateral Triangle - All the sides of this triangle are equal and all angles measure 60 degrees.
- Isosceles Triangle - Only two sides are of equal length in such a triangle.
- Scalene Triangle - All sides are of unequal length.

**Based on the measure of internal angles**

- Acute Triangle - All angles measure less than 90 degrees in this triangle.
- Right Triangle - One angle measures exactly 90 degrees and the remaining two form acute angles.
- Obtuse Triangle - One angle is obtuse and is greater than 90 degrees in such a triangle.

We can find the area of any of the above-listed triangles using the formula given below, provided the height is known.

Area = 1/ 2 × Base × Height

The same formula can be modified to find the base when we know the area and the height of a triangle.

Base = (2 × area) / height.

## Solved Examples on Triangle Calculator

**Example 1:**

Find the base of a triangle if the area and height of the triangle are 24 square units and 8 units respectively. Verify it using the triangle calculator.

**Solution:**

Given: Area = 24, Height = 8

Base = (2 × area) / height.

Base = 2 × 24 / 8 = 6

**Example 2:**

Find the base of a triangle if the area and height of the triangle are 57 units and 3 units respectively. Verify it using the triangle calculator.

**Solution:**

Given: Area = 24, Height = 8

Base = (2 × area) / height.

Base = 2 × 57 / 3 = 38 units

Similarly, you can try the triangle calculator and find the base of the triangle for the following:

- Area = 24, Height = 5
- Area = 20, Height = 10
