Finding perimeter on the coordinate plane may require the use of the distance formula: (2 x width) + (2 x height) III. Regular Polygon • A regular polygon is a polygon that is equiangular and equilateral. • A = ½ ap • a = Apothem is distance from the center of a polygon to one of its sides. • p = ns • n = number of sides • s = length of each side IV. Area of a Regular Polygon Area = ½ (p • a) p = perimeter a = apothem V. Square • Area of a square = a*a a = length of side

is the diameter of the circle. This formula gives an approximate pi value of 3.1605. An ancient mathematician Archimedes of Syracuse who lived between 287 - 212 BC derived the value of pi based on the area of a regular polygon inscribed within the circle and the area of a regular polygon within which the circle was circumscribed. Interesting Facts about Pi In 1706‚ an English mathematician introduced the Greek alphabet pi (π) to represent the said value. However‚ in 1737‚ Euler officially adopted

Q1 - Define engineering drawing. Why drawing is called universal language of engineers? Ans1:-A drawing drawn by an engineer having engineering knowledge for the drawing purposes is an engineering drawing. It is meant for communicating his ideas‚ thoughts and designs to others. Engineering drawing is a starting point of all engineering branches such as Mechanical‚ Production‚ Civil‚ Electrical‚ Electronics‚ Computer science‚ Chemical etc. It is spoken‚ read‚ and written in its own way.

Aron Persaud Absolute Value -How far a number is from zero. Example "-6" is 6 away from zero‚ but "-6" is also 6 away from zero. So‚ the absolute value of 6 is 6‚ and the absolute value of -6 is also 6. The symbol "|" is placed either side to mean "Absolute Value"‚ so we can write: |-6| = 6 Associative property- mathematical expression means that the order of the operations can be changed or regrouped so long as the operands (numbers or terms) are not changed. Example addition: (6 + 3) + 4

and to the University of Göttingen from 1795 to 1798. While in university‚ Gauss independently rediscovered several important theorems; his breakthrough occurred in 1796 when he was able to show that any regular polygon with a number of sides which is a Fermat prime and‚ consequently‚ those polygons with any number of sides which is the product of distinct Fermat primes and a power of 2 can be constructed by compass and straightedge. The discovery of Ceres led Gauss to his work on a theory of the motion

geographic features. Topology defines and enforces data integrity rules (for example‚ there should be no gaps between polygons). It supports topological relationship queries and navigation (for example‚ navigating feature adjacency or connectivity)‚ supports sophisticated editing tools‚ and allows feature construction from unstructured geometry (for example‚ constructing polygons from lines). It is the branch of geometry that deals with the properties of a figure that remain unchanged even

MTH 405 Midterm 16/3/2011 1. A specific area for the area of various polygons is the one for the area of a regular polygon. The setup and initial steps to creating the proof require a geometric approach that would otherwise make proving a big challenge. For example‚ a polygon with n sides is broken up into a collection of n congruent triangles‚ this geometric setup is key in reaching an easy solution for the area. The algebraic aspect comes into play when it comes to deriving the equation

Archimedes Background/Upbringing Archimedes was one of the most known and respected mathematicians of ancient Greece. He was born between the years of 290 and 280 BCE in Syracuse‚ Sicily which is currently known as Italy. His death took place in Syracuse‚ Sicily between the years of 212 and 211 BCE. In autumn of 212 or the spring of 211 Syracuse was taken over by Roman General Marcus Claudius Marcellus (Encyclopedia Britannica‚ n.d). It was during the cities take over that Archimedes was killed
