I seems you know wat you must do, dynamically allocate.

struct {
    float *xpoint;
    float *ypoint;
    }shape[10];

now just before you assign them,
don't forget to include stdlib.h,

shape[1].xpoint = malloc(sizeof(float) * 9);
shape[1].ypoint = malloc(sizeof(float) * 9);
shape[2].xpoint = malloc(sizeof(float) * 25);
shape[2].ypoint = malloc(sizeof(float) * 25);

you should check the return of malloc in case it's null for each.

you can then shape[1].xpoint[0] = 1.345;
             shape[1].xpoint[1] = 1,2353;
             ...
