In a ΔABC, it is given that AB = AC and AD is drawn perpendicular to BC. D is not the mid-point of BC.
False
We have, AB = AC
⇒ A is equidistant from B and C.
⇒ A lies on the perpendicular bisector of BC. (Since the points equidistant from two given points lie on the perpendicular bisector of the line segment joining them).
But, AD is perpendicular to BC. Therefore, D is the mid-point of BC.
