1. What is a polygon and how many sides can it have?A polygon is a flat shape made of straight edges that form a closed loop. The number of sides is the same as the number of corners, and polygons can have any number of sides, even a hundred or more.
2. Why do polygons have names like triangle, quadrilateral, and pentagon?The names come from Greek numbers: triangle has 3 sides, quadrilateral 4, pentagon 5, and so on. The prefix tells you how many sides the shape has.

Planar Figure: A geometric shape that lies entirely within a single flat plane.
Euclidean Geometry: The study of geometry based on the axioms and postulates developed by the ancient Greek mathematician Euclid.
Convex Polygon: A polygon where all interior angles are less than 180 degrees, and all diagonals lie within the polygon's interior.
