Mathematics Knowledge

Yesterday I presented a question on triangles.  As an ASVAB tutor, I remind the students in my course of the importance of knowing about triangles.  I remind them to know the different types of triangles, the different types of angles in triangles, the rules for angles in a triangle, and Pythagorean theorem.  The question for yesterday is: What triangle has all 3 sides and all 3 angles equal?  A triangle that has 3 equal sides and 3 equal angles is an equilateral triangle
