Given points ,
,
,
find the direction vector of the line passing through the point
and the midpoint of
the segment (i.e. the
median of the triangle
through the vertex ).
Given points ,
,
,
find the direction vector of the line passing through the point
and perpendicular
to the segment
(i.e. the line which contains the altitude of the triangle
through
the point ).
Consider the points ,
,
and the
triangle .
Find the direction vector of the line which is the perpendicular bisector of the side
(i.e. the line through the midpoint of the side
which is perpendicular
to the segment ).
Consider the points ,
,
and the
triangle .
Find the direction vector of the line which is the bisector of the angle
(i.e. the line which splits the internal angle at the point
into
two angles with equal measures).
