|Triangle Incircle Calculator: Radius, Area, and Ratio
The Triangle Incircle Calculator is a tool that allows you to determine the properties of the incircle of a triangle based on its side lengths. By entering the lengths of the three sides, this calculator calculates the radius and area of the incircle, which is the largest circle that can fit inside the triangle.
An online calculator calculates a polygon area, given lengths of polygon sides and diagonals, which split polygon to non-overlapping triangles.
|The area of a convex polygon from the coordinates of the vertices on the plane
This online calculator calculates the area of a convex polygon from the coordinates of the vertices. A convex polygon is built from the vertices using the Jarvis March Algorithm (or Gift Wrapping Algorithm)
