A triangle is a two-dimensional simplex.
Triangles are one of the three regular polygons that can tile the plain, forming the triangular tiling.
Equations
- The area of an equilateral triangle with side length l is:
√3∕4 · l2
- The area of an arbitrary triangle, where a and b are two sides of the triangle and C is the angle between them, is:
1∕2 · ab · sin C
Dissection
The equilateral triangle of side 1 may be dissected into 3× triangle with sides 1, √3/3, √3/3 and angles 30°, 30°, 120°.
