The missing step in the given proof is that angle 4 = angle 16. Reason: transitive property of equality.
How to illustrate the information?
It should be noted that angle 4 and angle 8 as well as 8 and 16 are congruent as they are corresponding angles.
Therefore, the missing step in the given proof is that angle 4 = angle 16. Reason: transitive property of equality.
Therefore, 15 and 4 will be equal to 180 since they are supplementary angles.
