How many sides does a quadrilateral have?

1. 3

2. 4

3. 5

4. 6

The correct answer is: 4

A quadrilateral is defined as a polygon that has exactly four sides. This characteristic is fundamental to its definition in geometry. Each side of a quadrilateral connects to two vertices, forming four angles at those vertices. Common examples of quadrilaterals include squares, rectangles, and trapezoids, all of which illustrate that a quadrilateral consistently maintains four sides. Therefore, the correct answer is that a quadrilateral has four sides.
