Final answer:
Vertical angles are congruent, while linear pairs assist in finding angle measures of intersecting lines.
Explanation:
Vertical angles and linear pairs play a crucial role in determining angle measures created by intersecting lines. Vertical angles are always congruent, meaning they have the same measure. When two lines intersect, the linear pair property helps us find the angles formed on either side of the intersection, ensuring that their measures sum up to 180 degrees.
