It is the vertex whose plural is vertices
An endpoint where two edges intersect on a polyhedron is called a vertex.
Such a point is called the orthocenter. Even the fact that all three altitudes intersect at a point is quite interesting because only two lines are guaranteed to intersect at a point, but we have three.
Vertex
The intercept
The point of intersection.
The point where the three altitudes of a triangle intersect is called the orthocenter. This can be located either inside or outside of the triangle.
Two planes that intersect are simply called a plane to plane intersection. When they intersect, the intersection point is simply called a line.
a four way intersection.:D
The lines that intersect to Form A right triangle are called Perpendicular Lines; the resulting meeting point of these two lines is called the vertex of the angle.
Two circles that don't have the same center point are called "non-concentric circles." These circles can have different radii and may or may not intersect each other. If they intersect, they will do so at two points, one point, or not at all, depending on their sizes and positions.
the point of concurrency
Parallel lines, by definition, never meet or intersect, as they are always equidistant from each other. If lines do meet, they are not parallel. If two lines that are not parallel intersect at a single point, they are referred to as intersecting lines.
