OpenStudy (12g):

Write a proof to show that the diagonals of a parallelogram bisect one another. Be sure to create and name the appropriate geometric figures. This figure does not need to be submitted.

OpenStudy (12g):

your fast

OpenStudy (malcolmmcswain):

How many steps do they want?

OpenStudy (12g):

doesnt say

OpenStudy (malcolmmcswain):

Hmmm... well, this is going to be hard. o-o

OpenStudy (malcolmmcswain):

Ok, so step one. What are we given.

OpenStudy (malcolmmcswain):

Let's make a parrallelogram ABCD. |dw:1450384929769:dw| What do we KNOW right away about this figure?

OpenStudy (12g):

i found something

OpenStudy (malcolmmcswain):

?

OpenStudy (12g):
