There is also anglestriped in mp-tool with some examples. The second argument changes the angle.
path p, q ;
p := unitsquare scaled 4cm ;
z1 = point 3.6 of p ;
q := subpath (0,2) of p -- z1 -- cycle;
q := q shifted(-4cm,-4cm);
draw q anglestriped(1,180,6) withcolor blue;
draw p ;
(I have not yet found why the striped path q goes out of position. Looking at mp-tool may help.)

Try the mpost variable lableoffset := ? to adjust.
