# How did we calculate this triangle?

### 2. From side b, side c and median ma we calculate side a:

Now we know the lengths of all three sides of the triangle and the triangle is uniquely determined. Next we calculate another its characteristics - same procedure as calculation of the triangle from the known three sides SSS.
