True or false? The number of sides of a polygon is
equal to the number of vertices.
This question is asking us to think
about polygons. We’re being asked if the number of
sides a polygon has is the same as the number of vertices it has. Let’s draw some polygons to help us
think about the question. A triangle is a polygon with three
sides and three corners. So, this polygon has an equal
number of sides and vertices.
Quadrilaterals have four sides and
four corners. The number of sides and vertices
are equal. Pentagons are polygons with five
sides and five corners. The number of sides and vertices is
equal. A hexagon is a polygon with six
sides and six corners. The number of sides and the number
of vertices or corners is equal. And an octagon is a polygon with
eight sides and eight corners or vertices. The number of sides is equal to the
number of vertices. This statement is true. The number of sides of a polygon is
equal to the number of vertices.
