Answer:
angle 1 and angle 2 are supplementary angles
Explanation:
When the base of the angles forms a straight line, the sum of the angles is 180°. That's the definition of supplementary angles.
Complementary angles form a right angle. The sum of complementary angles is 90°
A slightly silly way to remember Complementary angles: The two angles look at each other and compliment each other saying, "You look all right to me!"
"Yes, we are so right together!"
