Polygons Names And Pictures: A Comprehensive Guide
Are you curious about the different types of polygons and their names? Look no further! In this article, we will explore the world of polygons and provide you with pictures and information to help you understand these fascinating shapes.
What is a Polygon?
A polygon is a two-dimensional shape with straight sides that are connected to form a closed figure. The word "polygon" comes from the Greek words "poly" meaning many and "gonia" meaning angle. Polygons can have any number of sides, but they must have at least three.
Triangle
A triangle is the simplest type of polygon, with three sides and three angles. Triangles can be classified based on the length of their sides and the measure of their angles. Types of triangles include equilateral, isosceles, scalene, acute, obtuse, and right triangles.
Equilateral triangles have three equal sides and three equal angles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides or angles. Acute triangles have all angles less than 90 degrees. Obtuse triangles have one angle greater than 90 degrees. Right triangles have one angle equal to 90 degrees.
Quadrilateral
A quadrilateral is a polygon with four sides and four angles. Quadrilaterals can be classified based on the length of their sides and the measure of their angles. Types of quadrilaterals include squares, rectangles, parallelograms, trapezoids, rhombuses, and kites.
Squares have four equal sides and four equal angles of 90 degrees. Rectangles have two pairs of opposite sides that are equal and four angles of 90 degrees. Parallelograms have opposite sides that are parallel and four angles that add up to 360 degrees. Trapezoids have one pair of parallel sides and four angles that add up to 360 degrees. Rhombuses have four equal sides and opposite angles that are equal. Kites have two pairs of adjacent sides that are equal.
Pentagon
A pentagon is a polygon with five sides and five angles. Pentagons can be classified based on the length of their sides and the measure of their angles. Types of pentagons include regular pentagons, irregular pentagons, concave pentagons, and convex pentagons.
Regular pentagons have five equal sides and five equal angles. Irregular pentagons have sides and angles of different lengths and measures. Concave pentagons have at least one angle greater than 180 degrees. Convex pentagons have all angles less than 180 degrees.
Hexagon
A hexagon is a polygon with six sides and six angles. Hexagons can be classified based on the length of their sides and the measure of their angles. Types of hexagons include regular hexagons, irregular hexagons, concave hexagons, and convex hexagons.
Regular hexagons have six equal sides and six equal angles. Irregular hexagons have sides and angles of different lengths and measures. Concave hexagons have at least one angle greater than 180 degrees. Convex hexagons have all angles less than 180 degrees.
Heptagon
A heptagon is a polygon with seven sides and seven angles. Heptagons can be classified based on the length of their sides and the measure of their angles. Types of heptagons include regular heptagons and irregular heptagons.
Regular heptagons have seven equal sides and seven equal angles. Irregular heptagons have sides and angles of different lengths and measures.
Octagon
An octagon is a polygon with eight sides and eight angles. Octagons can be classified based on the length of their sides and the measure of their angles. Types of octagons include regular octagons and irregular octagons.
Regular octagons have eight equal sides and eight equal angles. Irregular octagons have sides and angles of different lengths and measures.
Nonagon
A nonagon is a polygon with nine sides and nine angles. Nonagons can be classified based on the length of their sides and the measure of their angles. Types of nonagons include regular nonagons and irregular nonagons.
Regular nonagons have nine equal sides and nine equal angles. Irregular nonagons have sides and angles of different lengths and measures.
Decagon
A decagon is a polygon with ten sides and ten angles. Decagons can be classified based on the length of their sides and the measure of their angles. Types of decagons include regular decagons and irregular decagons.
Regular decagons have ten equal sides and ten equal angles. Irregular decagons have sides and angles of different lengths and measures.
Conclusion
Now that you have a better understanding of the different types of polygons and their names, you can impress your friends with your newfound knowledge. Whether you're working on a geometry project or just curious about shapes, polygons are a fascinating subject to explore. Remember, polygons can have any number of sides, but they must have at least three. So, the next time you come across a closed figure with straight sides, you'll know it's a polygon!
Happy learning!
