Oct 3, 2024 · This calculator helps you determine the area and perimeter of a scalene triangle using the side lengths. Calculation Formula. For a scalene triangle with sides \ ( a \), \ ( b \), and \ ( c \), the semi-perimeter \ ( s \) is calculated as: \ [ s = \frac {a + b + c} {2} \] The area \ ( A \) is then calculated using Heron's formula:
The calculator will try to find all sides and angles of the triangle (right triangle, obtuse, acute, isosceles, equilateral), as well as its perimeter and area.
Scalene triangle calculator diagram. You can lock a side or angle and animate the other sides and angles to get the triangle dimensions you need. Hold down Left or Right ALT or CTRL keys to lock a side or angle. A red circle will appear to mark the locked side or angle.
This free online scalene triangle calculator calculates the different properties of scalene triangle (such as area, in-radius, circum-radius and perimeter of scalene triangle) for you in less than a minute.

It is not possible for a triangle to have more than one vertex with internal angle greater than or equal to 90°, or it would no longer be a triangle.The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate...The sum of the lengths of any two sides of a triangle is always larger than the length of the third sidePythagorean theorem: The Pythagorean theorem is a theorem specific to right triangles. For any right triangle, the square of the length of the hypotenuse equals the sum of the squares of the length...There are multiple different equations for calculating the area of a triangle, dependent on what information is known. Likely the most commonly known equation for calculating the area of a triangle involves its base, b, and height, h. The "base" refers to any side of the triangle where the height is represented by the length of the line segment dra...
Median The median of a triangle is defined as the length of a line segment that extends from a vertex of the triangle to the midpoint of the opposing side. A triangle can have three medians, all of which will intersect at the centroid (the arithmetic mean position of all the points in the triangle) of the triangle. Refer to the figure provided belo...
The Scalene Triangle Calculator is a tool designed to help you quickly determine the characteristics of a scalene triangle based on the lengths of its three sides. A scalene triangle is one in which all sides have different lengths and all angles are distinct.
