Calculate triangle area from 3 sides

Please provide 3 values including at least one side to the following 6 fields, and click the "Calculate" button. A triangle is a polygon that has three vertices. A vertex is a point where two or more curves, lines, or edges meet; in the case of a triangle, the three vertices are joined by three line segments called edges. A triangle is usually referred to by its vertices. Furthermore, triangles tend to be described based on the length of their sides, as well as their internal angles. For example, a triangle in which all three sides have equal lengths is called an equilateral triangle while a triangle in which two sides have equal lengths is called isosceles. When none of the sides of a triangle have equal lengths, it is referred to as scalene, as depicted below. Tick marks on the edge of a triangle are a common notation that reflects the length of the side, where the same number of ticks means equal length. Similar notation exists for the internal angles of a triangle, denoted by differing numbers of concentric arcs located at the triangle's vertices. As can be seen from the triangles above, the length and internal angles of a triangle are directly related, so it makes sense that an equilateral triangle has three equal internal angles, and three equal length sides. Note that the triangle provided in the calculator is not shown to scale; while it looks equilateral and has angle markings that typically would be read as equal , it is not necessarily equilateral and is simply a representation of a triangle.

Privacy Policy. The area of a triangle can be calculated with the help of various formulas.

The 3 sides triangle area calculator is here to the rescue if you need to calculate the area of a triangle but only know the three side lengths. A good example is trying to figure out the area of a triangular-shaped room — with this calculator, you'll learn how to find the square footage of a triangle room. To calculate the area of a triangle using the three side lengths is surprisingly tricky. If we know the height , then the area is found by simply multiplying the height by the base length and dividing by two. What we have built is a triangle area calculator — 3 sides and without height.

Calculate triangle area from 3 sides

Let us learn how to find the area of triangle with 3 sides given; that is when the length of three sides of a triangle is given. The area of a two-dimensional, closed geometric figure is the amount of region enclosed by that figure. It is expressed in terms of square units. Generally, we find the area of a triangle by halving the product of base and height. The area of triangle with 3 sides was first derived by the Greek mathematician Heron of Alexandria. He gave a formula which could calculate the area of a triangle without any requirement of measure of angles or any other distances, rather than the length of the sides of the triangle.

Maths Games. Maths Program. Area of Triangle With 3 Equal Sides 5. Unlike the previous equations, Heron's formula does not require an arbitrary choice of a side as a base, or a vertex as an origin. How do I calculate the area of a right triangle? Heron's formula is used to find the area of a triangle that has three different sides.

This triangle area calculator can help in determining the triangle area. The basic triangle area formula needs to have a base and height given, but what if we don't have it? How can we calculate the area of a triangle with 3 sides only?

Simply enter the three side lengths, and the calculator will show the area result instantly. Refer to the figure provided below for clarification. How do I calculate the area of an equilateral triangle? Front page Area Calculator Area of triangle The length of the three sides. However, it does require that the lengths of the three sides are known. Generate random numbers 2. Then the square root is taken, and we divide it by four to get the area A A A. Unlike the previous equations, Heron's formula does not require an arbitrary choice of a side as a base, or a vertex as an origin. This is because there are infinitely many triangles with the same angles. Date Calculator 4. The third, missing side length will then be calculated for you.
