Arbitrary triangle online calculation
App description
The graph of the closed graph (including its inner region) consisting of three points that are not collinear on the plane and the line segments that are connected every two points is called a triangle. Composition triangle
each line segment is called the edge of a triangle. The common endpoints on the adjacent sides are called the vertices of the triangle. The angle between the two adjacent sides is called the inner angle of the triangle, referred to as three
angular angle. The angle between the extension of one side of the triangle and its neighbor is called the outer angle of the triangle. The triangle with A, B, and C as the apex is recorded as: △ABC.
A figure enclosed by three straight lines on a plane or three arcs on a spherical surface. The figure enclosed by three straight lines is called a plane triangle; the figure surrounded by three arcs is called
A spherical triangle, also called a triangle. △ABC..
Usage example

When the triangle three-point coordinates are known, input the three-point coordinates:
X Y
A: 5 8
B: 4 3
C: 2 6
Note
In the known conditions, input three conditions, click calculate to calculate the result, and the coordinates will be calculated, but the known conditions can not be all angle conditions.
Given the coordinates of three points, the results of each condition can also be obtained.
