A figure consists of four angles: two of the angles have a measure of 45* and the other two angles have a measure of 50*. Which two angle measures correspond to complementary angles?
Complementary angles are two angles whose measures sum up to 90 degrees.
In this case, the two angles that correspond to complementary angles are the ones with measures of 45 degrees, because 45 degrees + 45 degrees = 90 degrees.
