Angle Relationships in Parallel Lines and Triangles

Corresponding Angles: Angles that are located on the same side of a transversal and also on the same side of two parallel lines. These angles are equal in measure when the lines are parallel.
Alternate Interior Angles: Angles that are positioned on opposite sides of a transversal and are located between two parallel lines. These angles are also congruent when the lines are parallel.
Alternate Exterior Angles: Angles found on opposite sides of the transversal but situated outside the two parallel lines. These angles are equal in measure when the lines are parallel.
Same-Side Interior Angles: Angles that lie on the same side of the transversal and between the two parallel lines. The sum of these angles is supplementary (adds up to 180°) when the lines are parallel.
Congruent Angles: Angles that are identical in both size and shape. When two angles are congruent, they have the same angle measurement.
Adjacent Angles: These are pairs of angles that share a common side and a common vertex, yet do not overlap. They can be supplementary or not, depending on their measures.
Supplementary Angles: Two angles whose measures add up to exactly 180°. This relationship is significant in various geometric proofs and angle calculations.
