Getting perimeter coordinates of a polygon
Hi i need help on how to get the perimeter coordinates(on shape) and in shape coordinates of a polygon with 12 points of vertices, like a cross.
The shape of the polygon can be irregular but the points will not intersect.
The coordinates are input via user prompt and stored in 2 arrays

Consider the two points (x0, y0) and (x1, y1). To get the distance between them:
dist = pow(x1 - x0, 2) + pow(y1 - y0, 2).
@integralfx
That is not the formula for calculating the distance between two points.

dist = sqrt(pow(x1 - x0, 2) + pow(y1 - y0, 2));

Two points j and k.
Distance between the two:
dx = x[j] - x[k]
dy = y[j] - y[k]
distance = sqrt(dx*dx + dy*dy)
Remember for a closed perimeter you need to add the last side going from the last point back to the first.

What do these mean: "perimeter coordinates" and "in shape coordinates"?
What does it mean that "points will not intersect"?
