Question 1210540
<br>
In triangle ABC, let D be a point on side BC.  Select all the true statements.<br>
If AD is an altitude of triangle ABC, then AC > AD.
TRUE.  If AD is an altitude, then it is the shortest distance from A to any point on BC; in particular, it is shorter than AC.<br>
If AD is a median of triangle ABC, then BD > CD.
FALSE.  By definition, if AD is a median then BD = CD.<br>
If AD is an angle bisector of triangle ABC, then AB > BD.
FALSE.  If angle B is a right angle or an obtuse angle, then AB is always shorter than AD.<br>
