chapter 3 converses and theorems

Corresponding Angles Converse

If 2 lines are cut by a transversal so the corresponding angles are congruent, then the lines are parallel

Alternate Interior Angles Converse

If 2 lines are cut by a transversal so the alternate interior angles are congruent, then the lines are parallel

Alternate Exterior Angles Converse

If 2 lines are cut by a transversal so the alternate exterior angles are congruent, then the lines are parallel

Consecutive Interior Angles Converse

If 2 lines are cut by a transversal so the consecutive interior angles are SUPPLEMENTARY, then the lines are parallel

Linear Pair Perpendicular Theorem

If 2 lines intersect to form a linear pair if congruent angles, then the lines are perpendicular

Perpendicular Transversal Theorem

In a plane, if a transversal's perpendicular to one of 2 parallel lines, then its perpendicular to the other one

Lines Perpendicular to a Transversal Theorem

In a plane, if 2 lines are perpendicular to the same line, then they're parallel to each other
