In geometry, a vertical vertex typically refers to one of the points where two lines intersect, forming vertical angles. Vertical angles are the pairs of opposite angles created when two lines cross each other. These angles are always equal in measure. The term "vertical vertex" may also be used in other contexts, such as in 3D geometry or architecture, to describe the apex or top point of a shape or structure.
They can.
vector, vertex, vertical
No.
A cone has only one vertex (the apex).
minimum point
Yes, since the vertex is a point and the vertical angles share that point.
They can.
That is the correct spelling of "vertices", the plural of the term vertex.
have the same vertex. be congruent.
Vertical is the adjective form of the English noun vertex, which comes from the Latin word vertex. The root word is vertere, meaning "to turn".
It is called a vertex.
vector, vertex, vertical
No.
not all congruent angles are vertical angles. Vertical angles must share a vertex.
A cone has only one vertex (the apex).
A trapezium.
Well it could be complementary or supplementary because they don't have to share a vertex yet I think you mean something like the vertical angle. You can go research vertical angles. I'll give you a link for the vertical angles. http://www.mathsisfun.com/geometry/vertical-angles.html
