Periodic Billiard Paths in Triangles
... Let a point move on a frictionless plane bounded by a triangle If it hits a corner (a vertex), then it stops If it hits a side (an edge), then it changes its direction such that the angle of reflection is equal to the angle of incidence The path that the point follows is called a billiard path An in ...

... Then place the decimal point in the correct place in the quotient (i.e. over the decimal point in the dividend). Before you divide decimals, you should round to the nearest whole number and estimate the answer. This is a good way to be certain the decimal point has been placed in the correct place ...
