Question

Which type of angle is

Answer 1

Answer:

D - Angle ABC is a complementary angle.

Explanation:

Option A - Straight angles usually measure at 180 degrees and go in a straight line. In this example, that’s not the right answer.
Option B - Vertical angles are “pairs of opposite angles made by two intersecting lines”. This may look as though it’s a vertical angle, that wouldn’t be the case. So option B isn’t the right answer.
Option C - Right angles usually measure at 90 degrees, so you could say that this is right. But there are two angles that make up 90 degrees. In this case, you would have to SOLVE to get a 90 degree angle. So this option wouldn’t be correct.
Option D - Complementary angles are two angles that add to 90 degrees. In this problem, there are two angles that make up 90 degrees. Therefore, option D is the correct answer.
