Final answer:
When solving for missing angles and identifying relationships in parallel lines and transversals, we can use corresponding angles, alternate interior angles, supplementary angles, and alternate exterior angles.
Step-by-step explanation:
When solving for missing angles and identifying relationships in parallel lines and transversals, we can use the following concepts:
A) Corresponding angles: Corresponding angles are located in the same position on different parallel lines and are equal in measure.
B) Alternate interior angles: Alternate interior angles are located on opposite sides of the transversal and between the parallel lines. They are equal in measure.
C) Supplementary angles: Supplementary angles add up to 180 degrees. When a transversal intersects parallel lines, the pairs of alternate interior angles are supplementary.
D) Alternate exterior angles: Alternate exterior angles are located on opposite sides of the transversal and outside the parallel lines. They are equal in measure.
