WebbAnd now that we've defined right angle, I can give you another definition for an acute angle. An acute angle has a measure, or it's smaller, than a right angle. When you learn about … Webb1. Light travels in a straight line between any two points in space.This is the foundation of linear perspective: the behavior of light can be described through traditional Euclidean geometry.. When light encounters the naturally dull and rough surfaces of the physical world, it is reflected or scattered in all directions. This means light is always abundantly …
