A parallelogram has the vertices (0, 3), (3, 0), (0, -3) and (-3, 0). Determine what type of parallelogram. Find the perimeter and area.
I've plotted that points and from what I see it's a rhombus. But help with the second part?

hero · Answer

Perimeter means distance around
Area of Parallelgram = base times height

anonymous · Answer

Yes! But it does not give me neither the base nor height, so how do I find them?

hero · Answer

You have to draw diagonals

anonymous · Answer

Okay, I did that! Now what?

hero · Answer

The length of one diagonal will be the base. The length of the other diagonal will be the height.

hero · Answer

If you take advantage of the intersection point of the diagonals, that should give you an easier way to find the lengths of the sides using pythagorean theorem.

anonymous · Answer

it is also a square
diagnal length is 6
length of each side is 3*sqrt(2)

and angles are 90

anonymous · Answer

both diagonals are congruent and do bisect each other
