An altitude is a line that goes through a vertex of the triangle and is perpendicular to the opposite side.  This means that line AD is an altitude of triangle ABC.

An angle bisector is a line that cuts an angle in half.  So segment AB is an angle bisector of the angle DAC.

A median is a line that extends from a vertex to the midpoint of the opposite side of a triangle.  Therefore segment BG is a median of triangle EBC.

A perpendicular bisector is a line that extends from the midpoint of a triangle side at right angles.  Therefore, segment GF is a perpendicular bisector of triangle BFC.

Segment AD is an altitude of triangle ABC, segment AB is an angle bisector of the angle DAC, segment BG is a median of triangle EBC, segment GF is a perpendicular bisector of triangle BFC.
