Demystifying Polygons: Discovering the True Statements


Polygons are fundamental shapes in geometry that have intrigued mathematicians for centuries. From the basic properties of triangles and quadrilaterals to the complexities of polygons with numerous sides, these shapes possess unique characteristics and relationships that continue to captivate researchers and enthusiasts alike. In this article, we will delve into the world of polygons, uncovering three true statements that shed light on their fascinating nature.

Statement 1: Regular Polygons Possess Equilateral Sides and Congruent Angles

Regular polygons are defined as polygons with equal side lengths and congruent interior angles. For instance, a regular triangle, also known as an equilateral triangle, consists of three sides of equal length and three angles measuring 60 degrees each. Similarly, a regular quadrilateral or square exhibits four congruent sides and four right angles measuring 90 degrees each.

The concept extends to polygons beyond quadrilaterals as well. Regular pentagons feature five equal sides and interior angles of 108 degrees each. Hexagons exhibit six congruent sides with interior angles measuring 120 degrees each. The pattern continues as more sides are added to the polygon.

Statement 2: The Sum of Interior Angles in a Polygon Can Be Determined Using the Formula (n-2) * 180 Degrees

The sum of the interior angles in any polygon can be calculated using a simple formula: (n-2) * 180 degrees, where ‘n’ represents the number of sides or vertices in the polygon. This formula holds true for all polygons – whether they are regular or irregular.

For example, consider a triangle (a polygon with three sides). The formula becomes (3-2) * 180 degrees = 180 degrees, which is the sum of the interior angles. Similarly, for a square (a polygon with four sides), the formula translates to (4-2) * 180 degrees = 360 degrees, the total sum of interior angles.

Statement 3: Polygons Can Be Classified Based on Their Convexity

Polygons can be categorized into two broad classifications based on their convexity – convex and concave polygons. A convex polygon is defined as a polygon in which any line segment connecting two points within it lies entirely inside the shape. In other words, no part of such a line segment crosses outside the boundaries of the polygon.

On the contrary, concave polygons possess at least one line segment that extends outside their boundaries when connected between any two points within them. These segments are referred to as “reflex” edges. An easy way to identify concave polygons is by observing their indentations or “caves” along their perimeters.


Understanding polygons requires unraveling their intricate properties and relationships. In this article, we explored three true statements about polygons: regular polygons possess equilateral sides and congruent angles; the sum of interior angles can be determined using the formula (n-2) * 180 degrees; and polygons can be classified based on their convexity or concavity. By delving deeper into these concepts, we gain a clearer understanding of these geometric shapes and appreciate their significance in mathematics.
