A ten degree angle is complementary to an eighty degree angle. Complementary angles add up to 90 degrees, so 10 + 80 = 90.
80 degrees is the complement of 10 degrees, as both angles combined must be 90 degrees, a right angle.
a 90 degree angle is a perfect angle of a square so 80 degrees will be 10 degrees less.
