The angle of the altitude of Polaris is equal to the observer's latitude. However, this is only true if you are in the Northern Hemisphere. For example, at the North Pole it is directly overhead and at the equator it is on the horizon and at 45 degrees North it is 45 degrees above you.
The difference in a hemisphere and a sphere is the shape and the size. A hemisphere is half of a sphere.
A right angle is a angle with 90o
There is one face on a hemisphere.
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!(;
