Isogonal is a mathematical
term which means "having similar angles". It occurs in several contexts:
An Isogonal is also the name for a line connecting points at which the magnetic declination is the same.
Mathematics
Mathematics is the study of quantity, space, structure, and change. Mathematicians seek out patterns and formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proofs, which are arguments sufficient to convince other mathematicians of their validity...
term which means "having similar angles". It occurs in several contexts:
- Isogonal polygon, polyhedron, polytope or tiling.
- Isogonal trajectoryIsogonal trajectoryWhen a family of curves intersects another family at a specific constant angle α, the first family is referred to as an isogonal family of the second one, and in this case it is said that every family is an isogonal trajectory of the other. It is assumed that α is different from π/2; if α=π/2 both...
