Metric relations in right triangle

 

In the right triangle ABC with m(Inegalitati trigonometrice) = 90° we use known notatios:

AB = c, AC = b, BC = a;

r = circumradius;

la = bisecting length taken from the top A;

ma = median length from A;

ra = length side duly ex-inscribed circle radius BC;
