 this is what I get
this has 4 sides so it's still a square right?

anonymous · Answer

should C. definition of a square be the answer?

jim_thompson5910 · Answer

To show that it's a square, you have to show that all 4 angles are 90 degree angles and you have to show that all sides are congruent

aripotta · Answer

that's not a square

anonymous · Answer

oh ok so then the answer should be F. unfounded !!

jim_thompson5910 · Answer

this is what you get when you plot the points

anonymous · Answer

yupp! thats what I got too. so that means that is not a square because all 4 angles are not 90 degrees

jim_thompson5910 · Answer

exactly, plus the 4 sides aren't congruent to each other

anonymous · Answer

yupp so that makes the answer F because it is not a square
