Question 185476
 If possible, draw an equilateral quadrilateral that is not regular. If not possible, tell why. 
---------------------
I just looked up rhombus.  Its sides are equal, and there are 4 of them, but the angles are not equal, so it's not regular.
It's equilateral, but not equilangular.  --> if it possible.


Can you draw a polyhedron with 7 faces, 10 vertices, and 16 edges? If no, why not? 

I don't know.  You'll have to repost that one.
