7.2: Complementary & Supplementary Angles

Remember, adjacent angles are "next to" each other, in the sense that they share a common vertex and side, but don't overlap.

So, non-adjacent means that the angles are separate from each other and do not share a common vertex and side.

In the first examples, you will check if pairs of angles or complementary, supplementary, or neither depending on the sum of the angles.

In the next examples, you will write and solve equations to find the value of x. You did this yesterday too... so your equations will either add up to equal 90 or add up to equal 180.
