Pick the set of numbers which contain all perfect squares:

a. {2,4,8,16,32}
b. {10,20,30,40,50}
c. {1,2,3,4,5}
d. {81,16,25,49,1}

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
