orthocentric
Adjective (Mathematics, Geometry): Relating to or associated with the orthocenter — the point where the three altitudes of a triangle intersect. - The term "orthocentric" is used to describe properties, points, lines, or configurations that involve or are defined by the orthocenter of a triangle.
- (The orthocenter is the specific point where the lines from each vertex perpendicular to the opposite side meet.)
- (The set of four points — the three vertices and the orthocenter — forms an orthocentric configuration.)
- (This is true for acute triangles, where all altitudes intersect within the triangle.)
Orthocentric system: A set of four points on a plane such that each point is the orthocenter of the triangle formed by the other three points.
- The vertices of a triangle and its orthocenter together form an orthocentric system. (Each of the four points serves as the orthocenter for the triangle made by the remaining three.)
Orthocentric tetrahedron: In three-dimensional geometry, a tetrahedron where all four altitudes (lines from each vertex perpendicular to the opposite face) intersect at a single point.
- A tetrahedron with mutually perpendicular edges is an orthocentric tetrahedron. (Such a tetrahedron has a single orthocenter for all its faces.)
Orthocenter (noun): The point of concurrency of the three altitudes of a triangle.
- The orthocenter of a right triangle is at the vertex of the right angle. (In a right triangle, the orthocenter is the vertex where the right angle occurs.)
Orthogonal (adjective): Relating to or involving right angles; perpendicular.
- The altitudes of a triangle are orthogonal to the opposite sides. (Each altitude forms a right angle with the side it meets.)
- Perpendicular-related: involving lines that meet at right angles (though "orthocentric" is more specific to triangles and their altitudes).
- (No common idioms exist for "orthocentric"; it is a technical term used primarily in geometry and mathematics.)
