Circle Geometry (1 Viewer)

[Vampire]

I'm having trouble with these questions:

Prove the medians of a triangle concur.

Prove the altitudes of a triangle concur.

Any help is appreciated....

Here are 4 circle theorems relating to concurrence.
I think its very useful to go through these proofs as harder 3 unit geometry.
