Difference between median altitude & internal bisector:
1) Median: Line that cuts the opposite side into two equal parts.
2) Altitude: It is related to angle & line drawn from one vertex will be perpendicular or 90° to poosite Side.
3) Internal Bisector: It divides the angle into two equal half angles when line is drawn from any one of three vertex of traingle.
4) Median Can be altitude & internal bisector.
5) Altitude also can be median. But not necessary that it will be internal bisector.
6) Internal bisector can be median & altitide also.
7) If Two half equal angle, opposite side is divided into two equal parts & perpendicular to opposite side.
Then, Altitude=median=Internal Bisector.
