    the median form <C is the line joining C to the midpoint of AB

    first find the midpoint of AB then use the formula for the distance between 2 points

    lol i understand median and how to get it from the median equation using and b points. My brain didnt connect the median of Ab and c for some reason XD

    midpoint of line joining (x1y1) and (x2y2) = ( x1+x2) / 2 , (y1+y2)/ 2

    if the coordinates of the points are (x1y1) and (x2y2 length = sqrt( (y2-y1)^2 - (x2-x1)^2 )
