Some are normal lines, Some like to go off on tangents , And some form envelops . Geometry also involves angles. Some angles are really acute , while others are obtuse . When dealing with angles, finding the answer is called a coincidence . It is almost impossible to differentiate between A right angle, and a wrong angle.
Numbers can be inconsistant .
When you can't make up your mind, use indefinite form. And, of course, watch out for decomposition . Part of mathematics is realizing solutions. There is a whole section of mathematics that deals with the division of Pi . Another branch deals with logs and roots .
