how do i use at-least 8 points to make some sort of geometric figure that can be recognized by my teacher , which should be drawn only in quadrant 1 and not on an axis. a vertex matrix should be set u using this figure???????

Answer 1

Not knowing what your teacher will recognize, it's hard to say, but I'd guess an octagon would be easy enough.

Start with a square, with vertices at, say,

(1,1)(5,1)(5,5)(1,5)

Now add another four points near the midpoints of the sides, say at

(3,0)(6,3)(3,6)(0,3)

Now just put all those x,y pairs into a matrix.
