This determines the gradient of the required line. Use B\((6,3)\) and \(m\). The perpendicular bisector passes through the midpoint of AC. This determines the point on the required line.

OM is perpendicular to AB (meet at a right angle ... Since these properties allow us to form a right-angled triangle, often these questions use Pythagoras. The entrance to a tunnel is shown ...

For example, the system was able to prove a theorem about the angle bisector of a triangle, which was not given as a premise or a goal in the problem. The researchers hope that their system ...
