General----> Specific deductive reasoning logic to draw conclusions from statements already accepted as true. point -zero dimensions-has locations only-capital letter (A,B,C) line straight path with no thickness (one dimension)infinite number of pointsextended without end in both directions line segment part of a line thats bounded by two end points plane flat unbounded (infinite) surface with no thicknesstwo dimensional represented by a parallelogramcapital letter in corner colinear points contained by the same line coplaner points that contained in the same plane noncollinear points not on a single line concurrent lines that contain a common point ray part of a line that extends endlessly in one directionname using endpoints firstsymbol points to the right angle a pair of rays that share the same endpointsides: raysvertex common endpointname using 3 points polygon lies in a planebounded by line segmentstwo dimensional polyhedron lies in spacebounded by polygons (no curves)three dimensional perimeter sume of the lengths of its sidesmeasured in units area surface included in square units or units2 circle set of all points that are a fixed distance or radius from a given point in the plane. constructions created with straightedge and compass bisect to divide into two equal parts quadrilateral formula A= 1/4(a+c)(b+d) conditional statements consists of two clauses, one which begins with the word "if" or "when" or some equivalent word hypothesis the letter a or "if" conclusion the letter b or "then" Euler diagram uses circles to illustrate how conditional statements relate to each other converse statement found by interchanging the hypothesis and conclusion of the conditional statement contrapositive statement formed by interchanging the a and b and denying both inverse formed by denying both a and b syllogism an argument in the froma--> bb--> ca-->c Direct Proof argument of syllogism premises statements of the arguement conclusion conncets the first to the last theorem statement that is proved by reasoning deductively from already accepted statements Indirect proof assumption made at the beginning that leads to a contradiction. The contradiction indicates that the assumption is false and the desired conclusion is true circularity impossible to define everything without going around in circles undefined words pointlineplane postulate statement assumed to be true without proof "determine" if there are two points, then there is exactly one line that contains them Pythagorean Theorem a2+b2= c2(must be a right angle) Triangle Sum Theorem the sum of the angles of a triangle is 180o Circle Theorems if the diameter of a circle is d, its circumference is pi-dIf the radius of a circle is r, its area is pi-r2 AuthorAnonymous ID104760 Card SetMath Chapter 1 and 2 Descriptionilkjhgdfsdasfghjkl Updated2011-09-28T00:22:26Z Show Answers
