QuestionAnswer
Acute Angle an angle less then 90 degrees
Congruent Angles angles of the same measure
Coplanar points and lines on the same plane
Midpoint a point that divides a segment into two congruent segments, it BISECTS the segement
Perpendicular lines lines that intersect to form RIGHT angles
Ray a part of a line that consists of an INITIAL point and all points on the line that lie on one side of the initial point
Space boundless 3-dimesional set of all points
Angle two rays connected at their endpoints, the points where they connect is the VERTEX
Congruent Segments two segements with the same length, "~=" means "is congruent to"
Counterexample enough to disprove a conjecture
Obtuse Angle an angle greater then 90 degrees
Plane flat surface that has no thickness, it extends without end in ALL directions
Right Angle an angle that is 90 degrees
Angle Bisector cuts an angle into two congruent angles
Conjecture a conclusion reached through inductive reasoning
Inductive Reasoning is reasoning based on observed patterns
Opposite Rays start at the point...and go in oppsite directions
Point no length, width, or thickness, but has a position
Segment portion of a line between two points, called ENDPOINTS
Collinear Points points that lie on the same line
Coordinate a number that is associated with a point on a number line
Line no length, no width, or thickness, it extends without end in two directions
Parallel Lines COPLANAR lines the do not intersect
Postulate a statement accepted to be true without proof
Skew Lines NONCOPLANAR lines, therefore they are NOT PARALLEL and do not INTERSECT
