Polygon Names And Sides
Welcome to the world of polygons! A polygon is a flat shape with straight sides that are connected to form a closed shape. In this article, we will dive into the world of polygon names and sides. By the end of this tutorial, you will be able to recognize different polygons and their properties.
What is a Polygon?
A polygon is a closed two-dimensional shape made up of straight sides. The word "polygon" comes from the Greek words "poly" meaning "many" and "gonia" meaning "angle." Therefore, a polygon has many angles. Polygons can be classified based on the number of sides they have.
Types of Polygons
Triangle
A triangle is a polygon with three sides. It is the simplest polygon. The sum of all angles in a triangle is always 180 degrees.
Quadrilateral
A quadrilateral is a polygon with four sides. Some examples of quadrilaterals are squares, rectangles, rhombuses, and trapezoids. The sum of all angles in a quadrilateral is always 360 degrees.
Pentagon
A pentagon is a polygon with five sides. The sum of all angles in a pentagon is 540 degrees.
Hexagon
A hexagon is a polygon with six sides. The sum of all angles in a hexagon is 720 degrees.
Heptagon
A heptagon is a polygon with seven sides. The sum of all angles in a heptagon is 900 degrees.
Octagon
An octagon is a polygon with eight sides. The sum of all angles in an octagon is 1080 degrees.
Nonagon
A nonagon is a polygon with nine sides. The sum of all angles in a nonagon is 1260 degrees.
Decagon
A decagon is a polygon with ten sides. The sum of all angles in a decagon is 1440 degrees.
Regular vs. Irregular Polygons
A polygon is regular if all its sides and angles are equal. An irregular polygon has sides and angles of different lengths and measures. Regular polygons can be inscribed in a circle, meaning that all the vertices of the polygon lie on the circumference of a circle.
Conclusion
Congratulations, you have made it to the end of this tutorial! You now know the names and properties of different polygons. Remember, a polygon is a flat shape made up of straight sides. Polygons can be classified based on the number of sides they have. Regular polygons have equal sides and angles, while irregular polygons have different sides and angles. Keep practicing and you will be a polygon master in no time!
Happy Polygon-ing!
