Best Answer

A pentagon has five sides and angles, and an octagon has eight sides and angles. Together this adds up to a total of 13 angles. One trick to remember how many angles and sides a polygon has is to look at the Latin roots. For example penta- is a prefix meaning five and octa- is a prefix signifying eight.
