The first idea that comes to my mind is to use the distance formula.

anonymous · Answer

your answer is$$US=\sqrt{(3-6)^{2}+(3-1)^{2}}=\sqrt{9+4}=\sqrt{13}$$

anonymous · Answer

draw the points on a sheet and you can identify the diagonals.

median to AB =
median to BC =
median to CA =

anonymous · Answer

A median is a line segment and you're looking for the lenght of a segment line.

anonymous · Answer

in the case of a right line you can find its lenght by using the distance formula.
