6 1 Practice the Polygon Angle Sum Theorems

Introduction to 6 1 Practice the Polygon Angle Sum Theorems:

Polygons are a basic concept in geometry and understanding their properties is imperative in various fields such as architecture, engineering, and science. One of the critical aspects of understanding polygons is the angle sum theorems. Polygon angle sum theorems are a set of fundamental principles used to calculate the interior and exterior angles of polygons.

In this article, we will examine the importance of understanding polygon angle sum theorems, outline the basic properties of polygons, explain the concept of angle sum theorems, and provide an overview of the 6 1 practice approach to solve the polygon angle sum theorem problems.

Understanding Polygons:

Polygons are polygons are shapes that are enclosed by straight lines. The term polygon is derived from two Greek words, poly, meaning “many,” and gon, meaning “angles,” as polygons are shapes with many angles. A polygon is classified according to the numbers of sides, angles, or vertices.

Some polygonal classifications comprise triangle, quadrilaterals, pentagon, hexagon, heptagon, octagon, nonagon, decagon, and so on. The properties of polygons include line symmetry, rotational symmetry, area, perimeter, and properties of their corresponding angles and vertices.

Polygon Angle Sum Theorems:

The Polygon Angle Sum Theorem states that the sum of all the interior angles in a polygon is equal to the total sum of (n-2) right angles, where n is the number of sides in the polygon.

In other words, to obtain the sum of the interior angles of a polygon, you subtract two from the number of sides and multiply the result by 180 degrees. The Exterior Angle Theorem states that the exterior angle of a triangle is equal to the sum of the two interior opposite angles of the triangle. The sum of the exterior angles of a polygon is 360 degrees.

The practical applications of polygon angle sum theorems include working out the angles of irregular, convex, or concave polygons. By using the angle sum theorem, one can determine the relationships between angles and sides of various polygons.

The 6 1 Practice Approach:

The 6 1 Practice approach is an effective strategy to solve polygon angle sum theorem problems. This approach involves six essential steps – examining the problem, searching for a pattern or relationship, predicting the results, verifying the prediction, justifying the results, and generalizing the solution. These steps prepare the students for various problem-solving techniques and ensure they gain critical thinking skills to tackle more complex geometric concepts.


The importance of understanding polygon angle sum theorems cannot be overstated. They form the foundation of fundamental geometrical concepts. By understanding the concepts in this article, you will learn to approach geometry problems methodically and efficiently.

We hope that the 6 1 Practice approach will help students realize the relevance of geometry and not simply memorize formulas. Solving and practicing sums related to polygon angle sum theorems can be a fun and engaging experience, and the more you practice, the more familiar you become with the subject. We recommend exploring various resources, such as textbooks, online references, and other interactive tools, to deepen your understanding of polygon angle sum theorems.
