Geometry Unit 5: Parallel Lines and Transversals

Study Notes

Parallel Lines and Transversals

Parallel Lines: Lines that remain equidistant and never intersect within the same plane.
Transversal Line: A line that crosses two or more lines, typically creating angles with parallel lines.

Angle Relationships

Congruent Angles: Angles that have equal measures, indicating they are the same size.
Intersecting Lines: Two lines that meet or cross, resulting in four formed angles.
Vertical Angles: Opposite angles formed where two lines intersect; they are always congruent.

Types of Angles in Relation to Parallel Lines

Corresponding Angles: Angles that occupy the same position on different parallel lines when intersected by a transversal.
Alternate Interior Angles: Angles located between two lines on opposite sides of the transversal; they are equal when lines are parallel.
Alternate Exterior Angles: Angles located outside the two lines on opposite sides of a transversal; they are also congruent when lines are parallel.
Same Side Interior Angles: Two angles that are on the same side of the transversal and between the parallel lines; they are supplementary.
Same Side Exterior Angles: Two angles that are on the same side of the transversal and outside the parallel lines; they are also supplementary.

Additional Angle Concepts

Consecutive Angles: Angles that share a side, which can apply to various angle relationships.
Adjacent Angles: Two angles that share a common side and vertex, positioned next to each other.
Supplementary Angles: Two angles that sum up to 180 degrees, typically forming a straight line when combined.
