DUE IN 6 MINUTES!! Which diagram provides a counter example to the statement below?

“Supplementary angles are never congruent.”

Two or more angles are supplementary if and only if they can add up to .  Thus, the appropriate option would be C.

Supplementary angles are angles that add up to the value of angle on a straight line i.e .

Congruent property of angles implies that they have equal value.

Thus, the given statement that: “Supplementary angles are never congruent”, implies that they can not be equal in value. Thus the contrary to the statement would be: “Supplementary angles are sometimes congruent.”

Considering the figures given in the question, the counter example to the given statement is the figure in option C. . Because angle 1 and 2 are approximately equal.
