Many results in geometry can be shown or demonstrated by construction and measurement. For example‚ we can draw a triangle and measure the angles to show or demonstrate that the angle sum of a triangle is 180 ° . However this does not prove that the angle sum of any triangle is 180 ° . To prove this and other geometrical results we use a process called deduction ‚ in which a specific result is proved by reasoning logically from a general principle or known fact. When setting out proofs

Assignment 12 Name: Wendy Number: 100501042 Real Life vs Virtual Life For many‚ the first thing they do to start a day is logging into their Facebook account to check out news feeds. After catching up with all their friends’ updates‚ they go to the virtual farm or restaurant that they are running and begin the works. Meanwhile‚ they are preparing for their real-life exam or meeting. But things used to be a lot easier when there were no Facebook and Farm Ville. With the popularity of social

Real Life versus Perfect Life Have you ever thought about how your real life would compare to your perfect life? Seven years ago I actually thought about this. When I was 21 years old I had my first child‚ a son Jayson Alexander Raney. I was working as a cashier at Food Lion‚ and my boyfriend was working at Advance Auto Parts. Our home was a two bedroom apartment that we shared with his mother. I knew that we weren’t financially prepared to provide for our son. I enrolled at Robeson Community College

Elliptic geometry (sometimes known as Riemannian geometry) is a non-Euclidean geometry‚ in which‚ given a line L and a point p outside L‚ there exists no line parallel to L passing through p. Elliptic geometry‚ like hyperbolic geometry‚ violates Euclid’s parallel postulate‚ which asserts that there is exactly one line parallel to L passing through p. In elliptic geometry‚ there are no parallel lines at all. Elliptic geometry has other unusual properties. For example‚ the sum of the angles of any

"The applications of geometry in real life are numerous. Nearly everyday people are faced with major and minor issues that require the use of geometry. Some of these include finding the square footage of a home‚ determining the volume a container or deciding how much tile is needed to put in a new kitchen floor. The square footage in a home is often determined by length and width of each room combined from the exterior walls. Without geometry we would never know how much square footage of paint to

Geometry Honors Component I know you need to know how to read a write for life‚ but how in the world does math come into play anywhere in life? Believe it or not math is actually very important‚ it’s kinda like a third language. You need math so you can see how much groceries are or to even make or design a building. This math is also known as algebra and geometry. No you may not uses algebra and geometry in the store but you will use it in sport and jobs like Civil Engineer or Architecture. Architecture

Non-Euclidean geometry is any form of geometry that is based on axioms‚ or postulates‚ different from those of Euclidean geometry. These geometries were developed by mathematicians to find a way to prove Euclid’s fifth postulate as a theorem using his other four postulates. They were not accepted until around the nineteenth century. These geometries are based on a curved plane‚ whether it is elliptic or hyperbolic. There are no parallel lines in non-Euclidean geometry‚ and the angles of triangles

Geometric constructions involve drawing geometric shapes that satisfy certain requirements (onlinemathlearning.com). The main focus in construction is on equidistance and co-linearity. This is done through the use of certain tools namely the compass and the straight edge. It is used to construct angles‚ planes figures and segments. This mathematical skill is applicable in many fields such as architecture‚ engineering and construction just to name a few. Base on the fact that geometric construction
