will mark you the brainliest! Help! which of the following correctly identifies angles that add up to 90 and 180

1. adjacent angles, congruent angles
2. complementary angles, vertical angles
3. supplementary angles, complementary angles
4. vertical angles, adjacent angles​

Answer 1

Answer: supplementary angles

Step-by-step explanation:

Answer 2

Answer:

3. supplementary angles, complementary angles

Step-by-step explanation:

In a right angled triangle, the two non-right angles are complementary, because in a triangle the three angles add to 180°, and 90° has already been taken by the right angle.

Any two angles that add up to 180 degrees are known as supplementary angles.
