As an ASVAB tutor, I make sure to review geometry for the Mathematics Knowledge section of the ASVAB.  One important part of geometry is reviewing the names of shapes.  If you do not know the name of all the shapes, you could miss out on an easy question.  Questions on shapes could be about perimeter, area, or angle measures.  In my book, The ASVAB Tutor’s Mathematics Knowledge Study Guide, I included a list of shapes from 3 sided through 12 sided shapes.  Make sure you know the name of all the shapes.  Do you know how many sides an undecagon has?  I will post the answer and explanation tomorrow.
