# Online calculator for calculating the area of a triangle

This online calculator is specially designed to calculate the area of a triangle. Simply enter the base, height and angle of the triangle and the calculator will provide you with the corresponding area.

A triangle is a three-sided polygon. It is one triangle area calculator of the basic shapes in geometry. A triangle has three sides and three angles. The sum of the three angles of any triangle is always 180°.

The area of a triangle is determined by the length of its sides and the angle between them. The most common way to calculate the area of a triangle is to use the formula:

area = 1/2 * base * height

where base is the length of one side of the triangle and height is the length of the line perpendicular to the base and passing through the opposite vertex.

This formula works for all triangles, no matter what their shape. However, there are other formulas that can be used to calculate the area of a triangle, depending on the information that is known about the triangle.

For example, if the length of all three sides of the triangle are known, the Heron’s formula can be used to calculate the area of the triangle.

The Heron’s formula is:

area = sqrt(s * (s – a) * (s – b) * (s – c))

where a, b, and c are the lengths of the sides of the triangle and s is the semiperimeter of the triangle, which is equal to (a + b + c) / 2.

Another formula that can be used to calculate the area of a triangle is the formula for the area of a trapezoid. This formula can be used if the triangle is a right triangle and the length of the two sides that form the right angle are known, as well as the length of the base of the triangle.

The formula for the area of a trapezoid is:

area = 1/2 * (b1 + b2) * h

where b1 and b2 are the lengths of the two sides of the trapezoid and h is the height of the trapezoid, which is equal to the length of the altitude of the triangle.

There are also formulas that can be used to calculate the area of a triangle if the coordinates of the vertices of the triangle are

## What information is needed to calculate the area of a triangle

If you want to calculate the area of a triangle, you need to know the lengths of all three sides of the triangle. You can then use the following formula to calculate the area of the triangle:

Area = 1/2 * base * height

where base is the length of the triangle’s base and height is the triangle’s height.

If you don’t know the length of the triangle’s height, you can still calculate the area of the triangle using the following formula:

Area = 1/2 * base * sqrt(3/4 * base2 – height2)

where base is the length of the triangle’s base and height is the length of the triangle’s height.

## How accurate is the online calculator

When it comes to online calculators, there is always the question of accuracy. Can you trust the results you get from an online calculator? When it comes to something as simple as calculating the area of a triangle, the answer is generally yes – you can trust the results you get from an online calculator.

There are a few reasons why online calculators are generally accurate. First, the algorithms that online calculators use are typically very well-tested and reliable. Second, online calculators use a variety of sources to double-check their results. And third, most online calculators allow you to input the precision that you need, so you can be sure that you’re getting the level of accuracy that you need.

Of course, no online calculator is 100% accurate 100% of the time. But for simple calculations like the area of a triangle, you can generally trust the results you get from an online calculator.
