| Median of Triangle | Segment from vertex to midpoint of the opposite side |
| Altitude of a Triangle | Segment from a vertex perpendicular to the line containing the opposite side |
| Perpendicular Bisector of a Segment | a line, ray, or segment perpendicular to the segment at its midpoint |
| Distance from a point to a line | The length of the perpendicular segment from the point to the line |
| Angle bisector | A segment that bisects the angle |
| Hypotenuse-Leg Theorem | If the hypotenuse and leg of one right triangle are congruent to the hypotenuse and corresponding leg of another triangle, then the triangles are congruent. |
| Deductive Reasoning | Reasoning that leads to a conclusion based on a series of accepted or proven statements |
| Inductive Reasoning | Leads to a conclusion based on past observations, said conclusion cannot be stated with certainty. |
| SSS Postulate | If three sides of one triangle are congruent to three sides of another triangle the the triangles are congruent |
| SAS Postulate | If two sides and the included angle of one triangle are congruent to two sides and the included angle of another tirangle the two triangles are congruent. |
| ASA Postulate | If two angles and the included side of one triangle are congurent to two sides and the included angle of another triangle then the two triangles are congruent. |
