 inductive reasoning 1. look for a pattern 2. make a conjecture (unproven statement based on observations) 3. verify the conjecture conjecture an unproven statement based on observations colinear points points that lie on the same line coplanar points points that lie on the same plane intersection set of points the figures have in common postulates rules accepted without proof synonym=axioms axioms rules accepted without proof synonym=postulates theorems rules that are proved distance formula formula for computing the distance between two points in a coordinate plane congruent segments segments that have the same length angle 2 rays that have the same initial point (vertex) vertex initial point of angle RULER POSTULATE the points on a line can be matched one to one with real numbers. the real number that corresponds to a point is the coordinate of the point. The distance between points A and B, written as AB, is the absolute value of the difference between the coordinates of A and B. SEGMENT ADDITION POSTULATE If B is between A and C, then AB + BC = AC. If AB + BC = AC, then B is between A and C ANGLE ADDITION POSTULATE if P is in the interior of angle RST, then angle RSP + angle PST = angle RST
