Answer :
1. angle 2 and angle 3 are Supplementary angles. Correct option is D.
2. angle 2 and angle 4 are Vertical angles. Correct option is B.
1. Supplementary angles:
Two angles are said to be supplementary if the sum of their measures is equal to 180 degrees. In other words, when you add the measures of two supplementary angles, the result is a straight line (a straight angle). Supplementary angles do not have to be adjacent (next to each other), but they must add up to 180 degrees.
2. Vertical angles:
Vertical angles are a special type of angle pair that are formed by two intersecting lines. When two lines intersect, they create four angles around the point of intersection. Vertical angles are the opposite angles formed by these intersecting lines. They are always congruent, meaning they have the same measure.
