Question

Determine whether parallelogram JKLM with vertices J(-1, 1), K(4, 1), L(4, 6) and M(-1, 6) is a rhombus, square, rectangle or all three.
A. rhombus
B. square
C. rectangle
D. rhombus, square and rectangle

is it b?

Answer 1

if u want to find the distance between to points...
A and B where A(x1 , y1) and B( x2 , y2)
the length AB can find by....\[AB = \sqrt{(x_{1}) - x_{2})^{2} +(y_{1}- y_{2})^{2} }\]

Answer 2

now use this
and find the length of
JK
KL
LM
MJ

wt will u get ?

Answer 3

Don['t understand

Answer 4

this distance between 2 points AB can be find by using the coordinates of these 2 points... and the above mention equation can be use for it

Answer 5

and since u need to check whether JKLM is a square or rectangle or a rhombus.. u need to know the lengths of the sides of JKLM

Answer 6

JKLM is a parallelogram in Cartesian plane

Answer 7

i graphed it and i got a square

Answer 8

now if u know the lengths of the sides
JK , KL , LM , MJ .. u can decide what shape is this
to find the length of those 4 sides
u have to use the above equation...

that;s wt i tried to say

Answer 9

lol... i was suggesting this method to find it without graphing it.. but if u graph it and got a square.. it should be a square.. then dont use this.. :P

Answer 10

your using to much work my friend
