10 2D Geometric Shapes You Should Know
Geometric shapes are an essential part of mathematics, art, and design. They are used to create various forms and structures in different fields, including architecture, engineering, and graphic design. In this article, we will explore 10 common 2D geometric shapes that you should know.
1. Square
A square is a quadrilateral with four equal sides and four right angles (90-degree angles). All internal angles are equal to 90 degrees.
2. Rectangle
A rectangle is a quadrilateral with four sides and four right angles. The opposite sides of a rectangle are equal in length.
3. Triangle
A triangle is a polygon with three sides and three vertices. The sum of the internal angles of a triangle is always 180 degrees.
4. Circle
A circle is a set of points equidistant from a fixed point called the center. A circle has no beginning or end.
5. Oval
An oval is an elliptical shape with no sharp corners or edges. It is like a flattened circle.
6. Rhombus
A rhombus is a quadrilateral with all sides of equal length. Opposite sides are parallel, and opposite angles are equal.
7. Trapezoid
A trapezoid, also known as a trapezium, is a quadrilateral with two pairs of opposite sides. One pair is parallel, and the other pair is not.
8. Hexagon
A hexagon is a polygon with six sides and six vertices. It is a common shape in nature, often found in honeycombs and rock formations.
9. Octagon
An octagon is a polygon with eight sides and eight vertices. It is often used in architecture and design.
10. Pentagon
A pentagon is a polygon with five sides and five vertices. It is a common shape in nature and is often used in design and architecture.
These 10 2D geometric shapes are essential in various fields, including mathematics, art, design, and engineering. Understanding and recognizing these shapes can help you appreciate the beauty and complexity of the world around us.
