What is the minimum number of triangles required to triangulate an hendecagon?

9 (two less than the number of vertices in the polygon).


How do you determine number or vertices of a polygon?

You can dertimine a number of vertices a polygon has by counting all the dots around the shape


A polygon has 12 sides how many vertices does the polygon have?

Twelve. The number of sides and vertices in a polygon are always the same.


How does the number of vertices of a polygon compare to the number of sides of the same polygon?

They are equal.


How many vertices does a seven-sided polygon have?

A polygon has the same amount of vertices as it does sides, so it would have 7 vertices.


A polygon has fourteen vertices How many sides does the polygon have?

Fourteen. Each polygons has the same number of sides as it has vertices. Therefore, a polygon with 14 vertices must have 14 sides.


How many vertices would a 20 sided polygon have and why?

20, because a polygon has the same number of sides and vertices.


Which figures have the same number of sides vertices and angles?

Vertices and angles are the same thing. Any polygon has an equal number of sides and vertices (and, therefore, angles).Vertices and angles are the same thing. Any polygon has an equal number of sides and vertices (and, therefore, angles).Vertices and angles are the same thing. Any polygon has an equal number of sides and vertices (and, therefore, angles).Vertices and angles are the same thing. Any polygon has an equal number of sides and vertices (and, therefore, angles).


What is two polygons by the number of vertices and sides each has?

A polygon with three vertices and three sides is a triangle. A polygon with four vertices and four sides is a quadrilateral.


How do you get the of a center of a regular polygon?

If it is a polygon with an even number (>2) of vertices, join any two pairs of opposite vertices. These lines will meet in the centre. If it is a polygon with an odd number (>1) of vertices, join any two vertices to the midpoints of the opposite sides. These lines will meet in the centre.


How many vertices would there be if you had a 20-sided polygon?

Polygons have the same number of vertexes/vertices as the sides. So, A 20 sided polygon will have 20 vertexes/vertices.


A 20 sided polygon has how many vertices?

It has 20 vertices, the same as the number of sides.
