Supplementary angles always add up to

(a)  

What are vertical angles?

• A pair of adjacent angles formed by the intersection of two lines.

• A pair of angles formed by the intersection of two parallel lines.

• A pair of angles formed by the intersection of two perpendicular lines.

• A pair of non-adjacent angles formed by the intersection of two lines.
