dan815 · Answer

what stops you from fitting rectangles in here

phi · Answer

do you know what kind of angles are in a rectangle ?

anonymous · Answer

the top part

phi · Answer

all angles in a rectangle are how many degrees ?  90 degrees (a right angle)
if you have a shape that does not have a 90 degree angle the corner of a rectangle won't "fit"

phi · Answer

that is the explanation.  You have to think about it or play with shapes to understand it.
