App description

A closed pattern consisting of successively connecting three segments of a line that are not on the same line is called a triangle. A pattern of three straight lines on a plane or three arcs on a sphere. 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.

Triangle area \(S= \frac {bh}{2} \)

Triangle area \(S= \frac {1}{2} absinΑ \)

In the formula:

h=high;

a, b, c = the length of the corresponding angle A, B, C

Α = degree of angle A

Usage example

Click on "High and bottom length"

Input data:

High=5

Base edge = 4
