3 1) Number Properties i) Integers Numbers‚ such as -1‚ 0‚ 1‚ 2‚ and 3‚ that have no fractional part. Integers include the counting numbers (1‚ 2‚ 3‚ …)‚ their negative counterparts (-1‚ -2‚ -3‚ …)‚ and 0. ii) Whole & Natural Numbers The terms from 0‚1‚2‚3‚….. are known as Whole numbers. Natural numbers do not include 0. iii) Factors Positive integers that divide evenly into an integer. Factors are equal to or smaller than the integer in question. 12 is a factor of 12‚ as are 1‚ 2

12in-wide-material piece. Thus the areas of four different shapes were found. By process of elimination‚ the optimal area for each shape was found by deriving the equations of area as well as basic geometry. The shapes used for this project were a semi-circle‚ triangle‚ square‚ and rectangle. For all four shapes we maximized the area rather than the volume because the length of the gutter system does not play an important factor. For the semi-circle‚ it was easy to assume that the circumference was 24 inches

Sumerian astronomers introduced angle measure‚ using a division of circles into 360 degrees.[4]They and their successors the Babylonians studied the ratios of the sides of similar triangles and discovered some properties of these ratios‚ but did not turn that into a systematic method for finding sides and angles of triangles. The ancient Nubians used a similar methodology.[5] The ancient Greeks transformed trigonometry into an ordered science.[6] Classical Greek mathematicians (such as Euclid and Archimedes)

found an amazing fact about triangles: If the triangle had a right angle (90°) and you made a square on each of the three sides‚ then the biggest square had the exact same area as the other two squares put together! It is called "Pythagoras’ Theorem" and can be written in one short equation: a2 + b2 = c2 Note: 1. c is the longest side of the triangle 2. a and b are the other two sides Why Is This Useful? If we know the lengths of two sides of a right angled triangle‚ we can find the length

missing angles and triangles. This project is Rolling Down The Ramp.It’s about rolling an object down a piece of wood and math and science text books to stack it up. Triangles are always going to 180 degrees. There is three different types of angles in triangles acute‚ obtuse‚ and right angle. This project has to contain a triangle as the part of the ramp. Or like the open space between the board and floor. There is triangles in nature and all around us. The angles on the triangle are right‚ obtuse

the properties of a triangle. By definition a triangle is something with three sides. This cannot be denied about a triangle since it is the definition. But there are certain properties that hold true for all triangle that will also alway hold true for triangles that are not derived from its definition. For example‚ sin of an angle will always be equal to the opposite side of the angle divided by the hypotenuse of the right triangle. This will be true for all right triangles and the property cannot

September 11th is already a date engraved into every American citizen’s mind‚ but for Shoshana Hebshi this date has a new memory behind it. Could you imagine sitting on an airplane and minding your own business and still making other passengers uneasy because of your skin color?
