Recall that two angles are supplementary if the sum of their measures is exactly 180 degrees. This is the key property to check for each pair.
For each pair of angles, add their measures together. For example, for the first pair, calculate \(110^\circ + 70^\circ\).
Compare the sum of each pair to 180 degrees. If the sum equals 180 degrees, then the pair is supplementary.
Repeat this process for all given pairs: \(80^\circ + 10^\circ\), \(60^\circ + 30^\circ\), and \(45^\circ + 45^\circ\).
Identify which pairs have sums equal to 180 degrees. Those pairs are the supplementary angles.
