Chapter 1.5, Problem 44PPS

To determine

To identify the pair of supplementary angles.

Answer to Problem 44PPS

  $\angle 1$ and $\angle 2$ are supplementary and

  $\angle 3$ and $\angle 4$ are supplementary

Explanation of Solution

Given information:

  

Evaluation:

Supplementary angles are those angles whose sum is $180°$ .

Concluding from the figure,

  $\angle 1+\angle 2=180$

And $\angle 3+\angle 4=180$

Hence, $\angle 1$ and $\angle 2$ are supplementary and

  $\angle 3$ and $\angle 4$ are supplementary
