How many diagonals can be drawn from a vertex of an n gon?
n-3 diagonals. Of the n vertices of the polygon, you cannot draw diagonals to the two adjacent vertices since these are sides of the polygon and so not diagonals. And you cannot draw a diagonal from a vertex to itself. So those are three vertices that are ruled out, leaving n-3.
How many vertices does a prism have?
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).
Which has more vertices a shape with 4sides or a shape with 3 sides?
A shape with four sides has four vertices and a shape with three sides has three vertices, so a shape with four sides has more vertices than a shape with three sides.
Is half of a circle a polygon?
No. a polygon must have at least 3 sides
Does a polygon usually have more sides or more angles example?
A polygon has an equal number of sides and angles. For example, a triangle has 3 sides and 3 internal angles.
