A triangle that has the sides , , , semiperimeter , area , exradii , , (tangent to , , respectively), and where and are the radii of the circumcircle and incircle respectively, is equilateral if and only if any one of the statements in the following nine categories is true. Thus these are properties that are unique to equilateral triangles, and knowing that any one of them is true directly implies that we have an equilateral triangle. http://www.math.com/tables/geometry/areas.htm
WebMar 9, 2024 · A triangular pyramid that has equilateral triangles as its faces is called a regular tetrahedron. The volume of a tetrahedron with side of length a can be expressed as: V = a³ × √2 / 12, which is approximately equal to V = 0.12 × a³. For instance, the volume of a tetrahedron of side 10 cm is equal to V = 6³ × √2 / 12 = 18 √2,
