Answer:
The correct option is C. XV is an angle bisector.
Step-by-step explanation:
Altitude: A perpendicular line segment from any vertex of a triangle to the opposite side is called an altitude.
Median: A line segment from any vertex of a triangle to the opposite side, which divides that side is two equal parts is called median.
Angle bisector: A line segment from any vertex of a triangle to the opposite side, which divides the angle of vertex in two equal parts is called an angle bisector.
Perpendicular bisector: A perpendicular line segment from any vertex of a triangle to the opposite side, which divides that side is two equal parts is called perpendicular bisector.
From the given graph it is clear that the line segment XV divides the angle X is two equal parts,
[tex]\angle YXV=\angle ZXV=40^{\circ}[/tex]
Therefore, XV is an angle bisector and the correct option is C.
