anonymous · Answer

according to wikipedia the definiton of a square is a plane figure with four equal straight sides and four right angles. so which one do you think is the right answer?

anonymous · Answer

A. A quadrilateral could be so many things
B. a parallelogram with angles that are all the same
C. a four sided polygon with sides with the same length
D. a diamond-ish shape with the same angles

Sooo....

A. nope, it doesn't have to be just a square. It could be a number of things. But in the question is says it MUST be a square.
B. a parallelogram could have a number of different side lengths. So no...
C. squares are four sided and have sides that are the same length
D. diamonds can't have angles that are all equal- that isn't logical

Sooo... I would have to go with C. =D

But a parallelogram is a four-sided plane rectilinear figure with opposite sides parallel.

okay thanks guys!!! :D

anonymous · Answer

Good luck!

anonymous · Answer

Yes, but a parallelogram ONLY has to have parallel sides. Which means that, unlike a square, it's angles could be NOT the same. And in the question it says 'what answer MUST be a square'. And a parallelogram doesn't necessarily HAVE to be a square. Which rules it out. =D
