Question

when two lines intersect they form two pairs of vertical angles if the measure of <1 is 60° what is the measure of <2?

Answer 1

Let's remember the definition of Vertical angles.

Vertical angles are defined as those pairs of angles formed when two lines intersect each other. They are non-adjacent angles and they are congruent (which means that their measures are equal). Vertical angles also share the same vertex.

For this case, you can see two lines that intersect this
