Question

What are vertically opposite angles 

Answer 1

When two angles of two lines are directly facing one another, or opposite, hope this helps!

Answer 2

When two lines cross, there are four angles at the place where they cross.
Two angles that do NOT share a side are vertical angles. There are two pairs
of vertical angles where the lines cross.

Also, by the way, vertical angles are always equal to each other.  It's often
very helpful to know that.
