| A | B |
|---|
| Adjacent | Angle description that gives no information about measure |
| Complementary | 2 or more angles whose measures sum to 90 degrees |
| Linear Pair | Adjacent, supplementary angles |
| Supplementary | 2 or more angles whose measures sum to 180 degrees |
| Bisect | Anything that produces two figures of equal measure does this to the original figure |
| Vertical | Angles whose measures are always congruent but who only share 1 common point |
| Alternate Interior | Inside the intersected lines, opposite sides of the transversal |
| Alternate Exterior | Outside the intersected lines, opposite sides of the transversal |
| Corresponding | Both on top or both below the intersected lines, same side of the transversal |
| Consecutive Interior | Inside the intersected lines, same side of the transversal |
| Segment Addition | Postulate about finding part or whole of the distance between two given points |
| Angle Addition | Postulate to find part or all of two adjacent shapes formed by rays |
| Midpoint | Equidistant from the endpoints |
| Conditional | Any statement in "if, then" form |
| Congruent | Same size and shape |
| Similar | Same shape, proportional sized sides |
| Obtuse | A triangle with one angle greater than 90 degrees |
| Acute | Equiangular triangles are also this angle classification |
| Right | Measures 90 degress, or has an angle that measures this |
| Reflection | Equidistant from the defining line |
| Rotation | Equidistant from the defining center |
| Translation | Same distance and direction from the original figure |
| Image | Figure after a transformation |
| Dilation | The only transformation that doesn't have to be congruent |
| Transformation | Changes location in a coordiate plane, in one case the size may also change proportionally |
| Side Side Side | A triangle congruency AND similarity |
| Side Angle Side | A triangle congruency AND similarity |
| Angle Angle | A triangle similarity postulate that is NOT a congruency as well |
| Hypotenuse Leg | The triangle congruency theorem that could be called "SSA" |
| Angle Side Angle | A triangle congruency that is NOT a tirangle similarity |
| Perpendicular | Symbolized by an "upside down T" |
| Parallel | Lines whose slopes are congruent |
| Equilateral | All sides congruent |
| Equiangular | Regular polygons are also this |
| Isosceles | Equilateral triangles are always this too, but NOT vice versa |
| Scalene | Most right triangles are also this |
| Equidistant | The midpoint compared to the endpoints |
| Line of Reflection | MUST be identified for any reflection |
| Center of Dilation | MUST be identified for any dilation |
| Geometry | Mathematical study of physical characteristics and relationships |
