Subject: i cant figure these out... if someone could PLEASE help thatd be great!?
1. If ON=4x-5, LM=2x+4, NM=x+5, and OL=8y-7, find the values of x and

y given that LMNO is a parallelogram.

a)x=-1/2;y= 23/16

b)x=2;y=-16/33

c)x=9/2;y=33/16

d)x=9/2;y=-16/33

2.Consider the statement, "if a parallelogram is a square,then it is a

rhombus."

a)decide whether it is true or false.

b)Write a converse

c)decide whether the converse is true or false.

3.draw figure in a coordinate plane and write a coordinate proof

Given: Quadrilateral ABCD with A (-5,0), B (3,-1) C(6,1), D(-2,2)

Prove: ABCD is a parallelogram

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.
