A right angle is a angle with 90o
what angle does a hemisphere have what angle does a hemisphere have what angle does a hemisphere have
So basically , you have an right angle and another angle . You draw an right angle over the angle your looking at and if its smaller than the right angle then its an acute angle . If its bigger than the right angle then its a obtuse angle . GoodLuck!(;

An obtuse angle has no complementary angle.
