Answer:
B. ∠1 ≅ ∠2; alternate interior angles theorem
Explanation:
Assume the diagram is like the one below.
The blue lines are parallel, and the red line is a transversal.
∠s 1 and 2 are between the parallel lines but on opposite sides of the transversal.
They are alternate interior angles.
Pairs of alternate interior angles are congruent.
A. is wrong. Alternate interior angles are congruent.
C. is wrong. Consecutive exterior angles are outside the parallel lines and on the same side of the transversal. They are like the two angles marked with a blue x. They are supplementary.
D is wrong. Consecutive exterior angles are supplementary.
Answer:
Explanation:
Hello,
Among the options given on the attached document, since phenolic functional group is characterized by a benzene ring bonded with a hydroxyl group (C₆H₅OH) we can see that the first option correctly points out such description. Thus, answer is on the second attached picture. Other options are related with other sections found in eugenol that are not phenolic.
Best regards.
