Q: A: ### Quick Answer

**A triangle has three vertices.** A triangle consists of three lines, and the location where one line endpoint meets another line endpoint is called a vertex. A square consists of four vertices, while an octagon contains eight vertices.

Any polygon has the same number of vertices as it does sides; this is a constant that never changes, no matter how many lines are introduced into a polygonal shape.

A collinear vertice refers to a set of points that lie on the same straight line.

Triangles are classified by the length of their sides and by the interior angles of the corners.

## How many diagonals does a nonagon have?

A:A nonagon, or enneagon, is a polygon with nine sides and nine vertices, and it has 27 distinct diagonals. The formula for determining the number of diagonals of an n-sided polygon is n(n - 3)/2; thus, a nonagon has 9(9 - 3)/2 = 9(6)/2 = 54/2 = 27 diagonals.

## How many vertices does a hexagonal prism have?

A:

Full Answer >**A hexagonal prism has 12 vertices, along with eight faces and 18 edges.**This shape has two hexagonal sides, as well as size rectangular sides that connect the sides of the hexagons.Filed Under: - Q:
## How many vertices does a cube have?

A:

Full Answer >**A cube has a total of eight vertices, despite having six square faces that would all have four vertices of their own if pulled apart.**A cube has six square faces that are joined not only at the sides, but at the vertices, essentially resulting in two squares that are joined by four lines, one at each corner.Filed Under:
