## How to Find Complementary & Supplementary Angles

Show steps for angles that are:If the two angles are If we know the measure of one of the two angles, we can use it to find the value of the missing angle.

### Step 1. Determine the total angle measure.

__co__mplementary or form a

__co__rner (right angle), then the total angle measure is $90_{∘}$.

### Step 2. Find the value of the unknown angle.

$given angle+unknown angleunknown angle =90_{∘}=90_{∘}−given angle $
