Study Notes
Angles Relating to Transversals
- Alternate Exterior Angles: Formed on opposite sides of a transversal, located outside the intersected lines, and are congruent if the lines are parallel.
- Alternate Interior Angles: Found within the two lines on opposite sides of the transversal, these angles are also congruent when the lines are parallel.
- Corresponding Angles: Located on the same side of the transversal and same side of the intersected lines; these angles are congruent if the lines are parallel.
- Same Side Interior Angles: Situated within the two lines on the same side of the transversal; these angles sum up to 180 degrees (supplementary) when the lines are parallel.
Theorems and Postulates
- Corresponding Angle Postulate: States that if two parallel lines are intersected by a transversal, the corresponding angles formed are congruent.
- Alternate Interior Angle Theorem: Verified that the alternate interior angles are congruent when parallel lines are cut by a transversal.
- Alternate Exterior Angle Theorem: Confirms that alternate exterior angles are congruent under the same condition of parallel lines.
- Same Side Interior Angle Theorem: Indicates that same side interior angles are supplementary if two parallel lines are intersected by a transversal.
Definitions of Lines and Planes
- Transversal: A line that intersects two coplanar lines at two distinct points, creating various angles.
- Parallel Lines: Coplanar lines that do not meet or intersect, maintaining equal slopes.
- Perpendicular Lines: Lines that intersect to form a right angle; their slopes are negative reciprocals of each other.
- Skew Lines: Noncoplanar lines that are not parallel and do not intersect, such as Line ON and Line LP.
- Parallel Planes: Planes that do not intersect, like Plane MNR and Plane LPS.
- Perpendicular Planes: Planes that meet or intersect at right angles, for example, Plane SRN and PSR.
