The opposite angles, angles that are opposite of each other are when two lines cross. They are also known as vertical angles, because the two angles share the same corner. Opposite angles are also congruent angles, meaning they are equal or have the same measurement.

You use FOIL (first, outer, inner, last) to check your answer. Eg: (x-4)(x+3)then distribute by using FOIL to get 2 2 x +3x -4x -12 then simplify to get x -x -12
