| Question | Answer |
|---|---|
| Transversal | A line that intersects two coplanar lines at two distinct points |
| Segment | The part of a line consisting of two endpoints |
| Coplanar | Points and lines that lie on the same plane |
| Adjacent | Two coplanar angles with a common side, a common vertex, and no common points |
| Midpoint | A point ona segment that divides a segment into two congruent segments |
| Concave | A polygon with at least one diagonal that falls outside the polygon |
| Complementary | Two angles whose measures have a sum of 90 degrees |
| Obtuse | An angle whose measure is greater than 90 degrees |
| Corresponding | Two angles that are in the same position on a transversal |
| Straight | An angle whose measure is equal to 180 degrees |
| Skew | Two or more noncoplanar lines |
| Hypotenuse | The longest side of a right triangle |
| Orthocenter | The point of concurrency of the altitudes of a triangle |
| Parallel | Two or more coplanar lines that do not intersect |
| Centroid | The point of concurrency of the medians of a triangle |
| Altitude | The perpendicular segment from a vertex to the line containing the opposite side |
| Supplementaty | Two angles whose measure have a sum of 180 degrees |
| Median | A segment in a triangle whose endpoints are a vertex and the midpoint of the opposite side |
| Acute | An angle whose measure is less than 90 degrees |
| Concurrent | When three or more lines intersect at one point |
| Circumcenter | The point of concurrency of the perpendicular bisectors of a triangle |
| Vertical | Two angles whose sides form two pairs of opposite rays |
| Convex | A polygon with no diagonals that lie outside the polygon |
| Polygon | A closed plane figure with at least three sides that are segments, the sides only intersect at their endpoints |
| Inverse | Negates both of the hypothesis and conclusion of a conditional |
| Contrapositive | Switches the hypothesis and the conclusion and negates both of them |
| Converse | Switches the hypothesis and conclusion in an "if-then" statement |
| Incentor | The point of concurrency of the angle bisectors of a triangle |
| Conditional | Another name for an "if-then" statement |
| Midsegment | A segment in a triangle connecting the midpoints of two sides |
| Regular | A polygon with all sides and angles the same |
| Right | An angle whose measure is equal to 90 degrees |
| CPCTC | Used to prove angles or sides of triangles are congruent |
