Question

Three vertixes of a convex quadrilateral are fixed. Find the locus of the fourth vertex if the area of the quadrilateral is constant.

Answer 1

I came across a similar question somewhere. Wouldn't it be a line?

Answer 2

um theres several answers i think

Answer 3

what year are u in!

Answer 4

|1 1|
|0 1|
|x y|
|1 0|
|1 1|
0.5(1 + 1 - (x + y)) = ?
0.5(2 - x - y) = ?
1 - 0.5x - 0.5y = ?
-0.5y = 0.5x - 1
y = -x + 2
Not completely sure if this is correct, but that's what I got.

Answer 5

It would be a line most definitely.

Answer 6

What I did was use an example to see what I got.

Answer 7

Is this multiple choice?

Answer 8

nope.. well the answer says theres three cases to consider. first case answer is y=-2k/a k is constant

Answer 9

I'm sorry...you're gonna have to ask someone else for this one...the only thing I see is 'locus of points' which would mean a type of graph.
