**Keywords and Theorems**

- Parallel
- When two or more lines lie in the same plane and never intersect.

- Skew Lines
- Lines that are in different planes and never intersect.

- Parallel Postulate
- For a line and a point not on the line, there is exactly one line parallel to this line through the point.

- Perpendicular Line Postulate
- For a line and a point not on the line, there is exactly one line parallel to this line through the point.

- Transversal
- A line that intersects two distinct lines. These two lines may or may not be parallel.

- Corresponding Angles
- Two angles that are in the “same place” with respect to the transversal, but on different lines.

- Alternate Interior Angles
- Two angles that are on the interior of and , but on opposite sides of the transversal.

- Alternate Exterior Angles
- Two angles that are on the exterior of and , but on opposite sides of the transversal.

- Same Side Interior Angles
- Two angles that are on the same side of the transversal and on the interior of the two lines.

- Corresponding Angles Postulate
- If two parallel lines are cut by a transversal, then the corresponding angles are congruent.

- Alternate Interior Angles Theorem
- If two parallel lines are cut by a transversal, then the alternate interior angles are congruent.

- Alternate Exterior Angles Theorem
- If two parallel lines are cut by a transversal, then the alternate exterior angles are congruent.

- Same Side Interior Angles Theorem
- If two parallel lines are cut by a transversal, then the same side interior angles are supplementary.

- Converse of Corresponding Angles Postulate
- If corresponding angles are congruent when two lines are cut by a transversal, then the lines are parallel.

- Converse of Alternate Interior Angles Theorem
- If two lines are cut by a transversal and alternate interior angles are congruent, then the lines are parallel.

- Converse of the Alternate Exterior Angles Theorem
- If two lines are cut by a transversal and the alternate exterior angles are congruent, then the lines are parallel.

- Converse of the Same Side Interior Angles Theorem
- If two lines are cut by a transversal and the consecutive interior angles are supplementary, then the lines are parallel.

- Parallel Lines Property
- The Parallel Lines Property is a transitive property that can be applied to parallel lines.

- Theorem 3-1
- If two lines are parallel and a third line is perpendicular to one of the parallel lines, it is also perpendicular to the other parallel line.

- Theorem 3-2
- If two lines are parallel and a third line is perpendicular to one of the parallel lines, it is also perpendicular to the other parallel line.

- Distance Formula
- .
