because it wouldn't all fit
OpenStudy (dan815):
yes just find a way to explain why its not fitting though
OpenStudy (dan815):
use this as an example as to why fitting rectangles seems difficult use a triangle
OpenStudy (anonymous):

what stops you from fitting rectangles in here
OpenStudy (phi):
do you know what kind of angles are in a rectangle ?
OpenStudy (anonymous):
the top part
OpenStudy (phi):
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"
OpenStudy (phi):
that is the explanation. You have to think about it or play with shapes to understand it.
