A decagon is a 10 sided polygon that has 10 vertices and 1 flat face

A decagon.
A prism has 2n vertices, where n is the number of sides in its base polygon. This is because each side of the base polygon is connected to another side by a vertical edge, and each vertex is formed at the intersection of two edges. So, a prism with a pentagonal base would have 10 vertices (5 vertices from the base polygon and 5 vertices from the top polygon).
12 points * * * * * A decagon has 10 vertices (points) and 10 sides. A polygon with 12 is a dodecagon.
A decagon has 10 vertices and 10 sides
A diagonal line of a polygon is a line that joins any two vertices not already joined by a side. A polygon with n sides has n(n-3)/2 diagonals → a decagon has 10(10-3)/2 = 10 × 7 ÷ 2 = 35 diagonals
10 sides 10 corners (vertices), no intersecting lines a closed figure.The sides&angles are not necessarily equal, unless a regular polygon is specified. A five-pointed staractually is a 10-sided polygon (There are 5 vertices pointing 'out' and 5 pointing 'in').
10 side polygon is called decogon
10 ... any polygon it is 2 less than the number of sides or vertices wince they are the same.
