Chapter Three Postulates 3.1-3.2 and Theorems 3.1-3.4
Term | Definition |
---|---|
corresponding angles postulate | if two / / lines are cut by a transversal, then the pairs of corresponding angles are congruent |
alternate interior angles theorem | if two / / lines are cut by a transversal then the pairs of alternate interior angles are congruent |
consecutive interior angles theorem | if two / / lines are cut by a transversal then the pairs of consecutive interior angles are supplementary |
alternate exterior angles theorem | if two / / lines are cut by transversal, then the pairs of alternate exterior angles are congruent |
perpendicular transversal | if a transversal is perpendicular to one of the two / / lines, then it is perpendicular to the other line |
slopes of parallel lines postulate | slopes of parallel lines are / / if and only if they have the same slope |
