Lesson states a RECTANGLE is a SQUARE?
Answered
I graduated college nearly 20 years ago, but want to pursue an advanced degree in economics. Therefore, I am brushing up my math skills starting in... 3rd grade. Yes, 3rd to make sure I fill in gaps. Anyways, go to 3rd Grade Math and in Quadrilateral section the video at the end says a square is a rectangle.
But when I go to answer questions sometimes it says it's incorrect that a square is a rectangle? Which is it?
