ACKNOWLEDGEMENT subcontinent is the Indus Valley Civilization that flourished between 2600 and 1900 BC in the Indus river basin. Their cities were laid out with geometric regularity‚ but no known mathematical documents survive from this civilization. The oldest extant mathematical records from India are the Sulba Sutras (dated variously between the 8th century BC and the 2nd century AD)‚ appendices to religious texts which give simple rules for constructing altars of various shapes‚

Geometry Notes Second Semester I. Area‚ Surface Area and Volume & Circumference Circumference is the linear distance around the outside of a circular object. • C = π • d or π • 2r. • d = diamater or (radius • 2) • r = radius II. Perimeter Perimeter is the distance around a figure. * It is found by adding the lengths of all the sides. * Finding perimeter on the coordinate plane may require the use of the distance formula: (2 x width) + (2 x height) III.

(Allen‚ 1997‚ para. 2). For the earliest period of Greek mathematics‚ there are few primary sources of information. We are therefore forced to rely extensively on the Euclidean Summary of Proclus. This contains an outline of the development of Greek geometry from early times until Euclid (Allen‚ 1997). Thales is often considered to be one of the first Greek mathematicians. The proposition known as the “Theorem of Thales” states‚ “The diameter of a circle always subtends a right angle to any point

mathematician‚ often referred to as the "Father of Geometry". He was active in Alexandria during the reign of Ptolemy I (323–283 BC). His Elements is one of the most influential works in the history of mathematics‚ serving as the main textbook for teaching mathematics (especially geometry) from the time of its publication until the late 19th or early 20th century.[1][2][3] In the Elements‚ Euclid deduced the principles of what is now called Euclidean geometry from a small set of axioms. Euclid also wrote

Fermat’s last theorem Currently holding the world record for longest standing math problem ever‚ Fermat’s last theorem went unsolved for 365 years. Fermat’s last theorem was one of the largest white whales in the study of math. Over the centuries‚ thousands were puzzled by the impossible problem. From its conception to its solution‚ Fermat’s last theorem was one of the most difficult to solve yet easy to understand problems in mathematics. First‚ I will discuss the theorem and how it was introduced
