Answer: Complementary angles, adjacent angles
Step-by-step explanation:
Because of vertical angles, we know that the sum of angles 1 and 2 would be equal to 90 degrees, as the measure of right anglese is 90 degrees.
A pair of angles that sum to 90 degrees are otherwise called complementary angles.
These pair of angles are also adjacent because they have a common side/vertex yet do not intersect.
They are not vertical angles because they are not opopsite of each other.
They are not supplementary angles because they don't sum to 180 degrees.
