Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures cre
Andru [333]

Answer:

So when two lines intersect, it creates 4 angles. The angles that lie opposite to each other are congruent

If you know the measure of one angle in a linear pair, you can find the measure of the other because the sum of the measure of the two angles is 180 degrees. If you know the measure of one angle in a pair of vertical angles, you can find the measure of the other because they are congruent.
