Trithogonal

|
In geometry, three lines or planes (or a line and two planes) are considered trithogonal to each other if they form congruent adjacent angles. The term may be used as a noun or adjective. Thus, as an example, the line ABC is trithogonal to DEF through the point A. By definition, a line is infinitely long, and strictly speaking ABC and DEF in this example represent line segments of three infinitely long lines. Hence the line segment ABC does not have to intersect line segment DEF to be considered trithogonal lines, because if the line segments are extended out to infinity, they would still form congruent adjacent angles. If a line is trithogonal to another two, all of the angles created by their intersection are called right angles (right angles measure π/2 radians, or 90°). Conversely, any lines that meet to form right angles are trithogonal. ©026938 Prof Chunk.T.H©.Barrie.M.D©.Dr Mini-Whitey© |
