| A | B |
|---|
| inductive reasoning | making a prediction by looking at several examples |
| reflect | a flip |
| rotate | a turn |
| translate | a slide |
| transformation | reflection, rotation, and translation |
| image | the result of a transformation |
| symmetry | when a figure and its image coincide |
| collinear | on the same line |
| coplanar | in the same plane |
| intersect | share a point or line |
| parallel | two lines that never intersect |
| skew | two lines that are not parallel, but never intersect |
| ray | a part of a line with one endpoint |
| endpoint | a point at the end of a line segment or ray |
| segment | a part of a line with two endpoints |
| congruent segments | segments that are equal in length |
| angle | formed by two rays with a common endpoint |
| vertex of an angle | the common endpoint of two rays |
| congruent angles | angles that have the same measure |
| midpoint | point that divides a segment into two congruent segments |
| bisector of a segment | line, segment, ray, or plane that intersects a segment at its midpoint |
| bisector of an angle | ray or line that divides an angle into two congruent angles |
| hypothesis | if part of a conditional statement |
| conclusion | then part of a conditional statement |
| conditional statement | can be written in the form "if p, then q." |
| counterexample | an example for which the hypothesis is true but the conclusion is false |
