Draw the medians of the triangle.

This problem is the same as problem 20, except now we are to draw an obtuse triangle. First, draw the obtuse triangle. Next, draw the perpendicular bisectors of the triangle. With the help of the perpendicular bisectors, draw the medians of the triangle. The intersection of the medians of the triangle is the centroid of the triangle.
