Peter draws triangle abc and identifies a point that lies outside of triangle abc as the intersection of the medians of the triangle. could peter be correct?

  No

Step-by-step explanation:

Each median resides entirely within the triangle. The point of their intersection (the centroid) is always inside the triangle. The point Peter is describing is not the intersection of medians.

The intersection of altitudes may be outside the triangle, as may be the intersection of side bisectors. The latter is called the circumcenter.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
