Question

decide if this statement is valid or invalid. a polygon with more than 4 sides is not a quadrilateral. thus a polygon that has less then 4 sides is a quadrilateral.

Explanation:

Step1: Define quadrilateral

A quadrilateral is a polygon with exactly 4 sides.

Step2: Analyze first part

A polygon with more than 4 sides (e.g., pentagon, hexagon) is not a quadrilateral. This is correct as per the definition.

Step3: Analyze second part

A polygon with less than 4 sides (e.g., triangle - 3 sides, line segment - 1 side, angle - 2 sides) does not have 4 sides. So, it cannot be a quadrilateral. The second statement is wrong.

Answer:

Invalid
