Study Notes
Congruent Supplements Theorem
- States that if two angles are supplementary to the same angle, they are congruent.
- This theorem applies when angles are supplementary to either the same angle or congruent angles.
Converse of Congruent Supplements Theorem
- If two angles are congruent, they are supplementary to the same angle or to congruent angles.
Alternate Interior Angles
- Defined as the angles situated between two lines on opposite sides of a transversal.
- Useful in determining relationships between angles in parallel lines and transversals.
Alternate Exterior Angles
- These angles lie outside a pair of lines and on opposite sides of a transversal.
- They can help determine if lines are parallel based on their congruence.
Consecutive Interior Angles Theorem
- If a transversal intersects two parallel lines, the pairs of consecutive interior angles are supplementary.
- This theorem is key in analyzing angles formed by parallel lines.
Converse of Alternate Interior Angles Theorem
- If alternate interior angles created by a transversal are congruent, then the two lines being crossed are parallel.
Corresponding Angles Postulate
- States that if two parallel lines are intersected by a transversal, the corresponding angles formed are congruent.
- This postulate is pivotal in angle relationships within parallel line setups.
Converse of Corresponding Angles Postulate
- If two coplanar lines are intersected by a transversal and a pair of corresponding angles are congruent, then the lines must be parallel.
- This postulate aids in proving parallelism between lines based on angle measures.
