| Question | Answer |
|---|---|
| Acute Angle | an acute angle is an angle whose measure is between 0 and 90. |
| Angle | an angle is formed by two rays with the same endpoint. The rays are the sides of the angle and the common endpoint is the vertex of the angle. |
| Angle Bisector | an angle bisector is a ray that divides an angle into two congruent angles. |
| Collinear Points | collinear points lie on the same line. |
| Congruent Angles | congruent angles are angles that have the same measure. |
| Congruent Segments | congruent segments are segments that have the same length. |
| Conjectures | a conjecture is a conclusion reached by using inductive reasoning. |
| Coordinate | a coordinate is points on a line graph |
| Coplanar | coplanar are figures in the same plane |
| Counterexample | a counterexample to a statement is a particular example or instance of the statement that makes the statement false |
| Inductive Reasoning | inductive reasoning is a type of reasoning that reaches conclusions based on a patter of specific examples or past events. |
| Line | a line is undefined. You can think of a line as a great circle of a sphere. You can think of a line as a series of points that extended in two firections without end. |
| Midpoint | a midpoint of a segment is the point that divides the segment into two congruent segments. |
| Obtuse Angle | an obtuse angle is an angle whose measure is between 90 and 180. |
| Opposite Rays | opposite rays are collinear rays with the same endpoint. They form a line. |
| Parallel Lines | two lines are parallel if they lie in the same plane and do not intersect. |
| Perpindicular Lines | perpindicular lines are lines that intersect and form right angles. |
| Plane | a plane is undefined. A plane contains many lines and extends without end in the directions of its lines. |
| Point | a point is undefined. You can think of a poiny as a location. A point has no size. |
| Postulate | a postulate, or axiom, is an acceoted statement of fact. |
| Ray | a ray is the part of a line consisting of one endpoint and all the points of the line on one side of the endpoint. |
| Right Angle | a right angle is an angle whose measure is 90. |
| Segment | a segment is the part of a line consisting og two points, called endpoints, and all points between them. |
| Skew Lines | skew lines are kines that do not lie in the same plane. |
| Space | space is the set of all points |
