Kid: (looking at a quadrilateral with equal sides....a square for anyone who missed that lesson in school...) "how can I find x?"
Me: Well, if all sides are equal and this side is 2x + 5 and this side is 4x - 3 then how can we make an equation to solve for x?
Kid: (blank stare)
Me: So if this side is EQUAL to this side how can I make an equation, which has something EQUAL to something else, so I can solve for x?
Kid: (blank stare)
Me: So let's just say this side was 2x (points to one side) and this side was 10 (points to consecutive side) how would I solve for x?
Kid: (blank stare) ......x is 5
Me: GREAT! Now how did you get x = 5?
Kid: (blank stare)
Me: Just try your best.....
Oops, let me stop being caustic. Technically a quadrilateral with 4 equal sides could be a rhombus as well. I amend with: "a parallelogram with 4 congruent sides and angles".
