a baseball field has four bases that form the shape of a quadrilateral. If someone invented a new game similar to baseball that had an extra base in the field, what type of polygon would the bases form?

The new field would have five sides.

Explain please ;-;

It is pentagon

To determine the type of polygon formed by adding an extra base to a baseball field, we need to understand the properties and characteristics of polygons.

A polygon is a closed shape made up of straight line segments. The properties of a polygon are based on the number of sides it has. Let's consider the number of sides a polygon can have based on the information given:

- A triangle has three sides.
- A quadrilateral has four sides.
- A pentagon has five sides.
- A hexagon has six sides.
- And so on.

Since a baseball field with four bases already forms a quadrilateral, or a 4-sided polygon, adding an additional base would create a polygon with five sides.

Therefore, if someone invented a game similar to baseball but with an extra base, the bases would form a pentagon, which is a five-sided polygon.
