 acute angle a flat surface that has no thickness angle bisector a ray that divides an angle into two congruent coplanar angles collinear points distance and direction from the origin of a number line congruent angles a 180 degree angle congruent segments an angle between 90 and 180 degrees conjecture a 90 degree angle coordinate angle with the same measure coplanar part of a line consisting of two endpoints and all points between them counterexample noncoplanar lines inductive reasoning coplanar lines that do not intersect obtuse angle points that lie on the same line parallel lines an accepted statement of fact parallel planes a line, segment, or ray that is perpindicular to the segment at its midpoint perpindicular bisector part of a line consisting of one endpoint and all the points of the line on one side of the endpoint perpindicular lines reasoning based on patterns one observes plane points (or lines) that are in the same plane postulate a conclusion reached using inductive reasoning ray planes that do not intersect right angle a positive angle less than 90 degrees segment two segments with the same length skew lines two lines that intersect to form right angles straight angle an example for which the conjecture is incorrect
