In mathematics‚ the study of the circle has helped inspire the development of geometry‚ astronomy‚ and calculus. Early science‚ particularly geometry and astrology and astronomy‚ was connected to the divine for most medieval scholars‚ and many believed that there was something intrinsically "divine" or "perfect" that could be found in circles.

The aim of this task is to investigate geometric shapes‚ which lead to special numbers. The simplest example of these are square numbers‚ such as 1‚ 4‚ 9‚ 16‚ which can be represented by squares of side 1‚ 2‚ 3‚ and 4. Triangular numbers are defined as “the number of dots in an equilateral triangle uniformly filled with dots”. The sequence of triangular numbers are derived from all natural numbers and zero‚ if the following number is always added to the previous as shown below‚ a triangular number

Algebra Algebra was invented by the Muslim mathematician Al-Khwarizmi in the book he wrote in 820. Algebra is the Arabic word (aljabr) for "equation"‚ and the word "algorithm" comes from the author’s name‚ Al-Khwarizmi. He is rightly known as "the father of Algebra The roots of algebra can be traced to the ancient Babylonians‚ who developed an advanced arithmetical system with which they were able to do calculations in analgorithmic fashion. The Babylonians developed formulas to calculate solutions

The Five Platonic Solids The five platonic solids are the tetrahedron‚ cube‚ octahedron‚ dodecahedron‚ and a icosahedron. They are named for the greek philosopher Plato. Plato wrote about them in the Timaeus (c.360 B.C.) in which he paired each of the four classical elements earth‚ air‚ water‚ and fire with a regular solid. Earth was paired with the cube‚ air with the octahedron‚ water with the icosahedron‚ and fire with the tetrahedron. The fifth Platonic solid‚ the dodecahedron‚ Plato says that

Tessellations can be created with a variety of figures‚ including triangles‚ squares‚ trapezoids‚ parallelograms‚ or hexagons. Tessellations use forms of transformations to show the repetitions
