What do you KNOW about parallelgrams? In particular what is true about opposite sides?

Do you know the definition of rhombus? Does a square fit that definition? Do you know what the converse of a statement is? If you don't what could you do to find out?

What is the DEFINITION of parallelogram? What theorems do you know about parallelgrams? Do you know how to find the distance between two points given in coordinates? Do you know how to determine if two lines through two sets of points,given in coordinates, are parallel? i drew the figure but i dont know how to do the rest of that one.. and the other 2 i dont understand how to do.. if someone could please help me with these thatd be great.. thanks.
