All of the points on a parabola define a parabola. However, the vertex is the point in which the y value is only used for one point on the parabola.
In geometry, a corner refers to the point where two sides of a polygon meet, while a vertex refers to the point where two or more edges of a polyhedron meet. Essentially, a corner is a term used in 2D shapes like squares and triangles, while a vertex is used in 3D shapes like cubes and pyramids. Both terms describe points of intersection, but the distinction lies in the dimensionality of the shapes they refer to.

3. You cannot have a diagonal from a vertex to itself, nor to either of the two adjacent vertices (these would form sides of the polygon). So 3 out of the other vertices cannot be used. In a hexagon, that leaves 3 that can be used. Hence the answer.
. On these twelve meridians, there are nearly 2,000 points which can be used in acupuncture, with around 200 points being most frequently used by traditional acupuncturists
That's a numeric keypad.

The definition of vertices is the plural vertex. A vertex is point of intersection of two or more lines. A vertex can also be used to describe the angular point of a polygon, polyhedron, or other shape.
