Help ASAP please and explain if you can

Question thirteen is a right angle (because if you plot the pints, it obviously looks like a fit angle)
Question fourteen is c ( because when you plot all the points, the first two options don't make sense if side pq is congruent to qr, then we are left with options c and d. Option d forms a right triangle (and sides pq and qr can't be congruent) . Whereas in option c, it is mathematically possible for pq and qr to be congruent to one another)
Basically, all you have to do is plot the points for both questions and the answer will become obvious)
