As an ASVAB tutor, I remind my students of the importance of studying shapes for the Mathematics Knowledge section of the ASVAB.  Geometry is one of the important topics that appears on this section of the test.  In my book, The ASVAB Tutor’s Mathematics Knowledge Study Guide, I discuss the names of all the shapes and their formulas.  Today’s question asks which of the shapes is not a parallelogram.  To be able to answer this question, you need to be able to answer the question, “What is a parallelogram?”  Do you know the characteristics of a parallelogram?  Tomorrow I will present the answer and the explanation.
