This is a true or false thing for geometry

1) False
2) If two angles are 45 degrees then they are complementary and congruent.

Explanation: Complementary angles add up to 90 degrees and congruent angles are angles that are equal. Two 45 degree angles are equal to each other and add up to 90 degrees. The first statement is false because there are many combinations of angles that add up to 90 degrees that are not the same. (30 degrees and 60 degrees)

C. a,b, and d are not numbers. they are expressions.
