Triangle Area

triangle areaTriangle – is a geometric figure that has three points not lying on a single line and three segments that pairwise connect these points. The points of the triangle are called its vertices, and the segments – its sides.
Our online calculator will help you calculate the area of a triangle in just a few seconds. To do this, you need to enter certain data, namely the length of its base, represented by the Latin letter «a» and the height of the triangle, represented by the Latin letter «h».
The area of a triangle is calculated using the formula:formula triangle area, calculator.indicating that the area of a triangle is equal to the product of the length of its base and height divided by two.
