How will you find the point in side BC of ΔABC which is equidistant from sides AB and AC.

Answer :



In Δ ABC, draw bisector of BC which cuts it at D.


Take any point P on AD. Draw PN AB and PM AC.


In Δ APN and Δ APM


PNA = PMA = 90° ( by construction)


PAN = PAM ( AD is bisector of A)


AP = AP )( common)


Δ APN Δ APM (By AAS rule)


PN = PM ( By CPCT)


So, P is equidistant from AB and AC.


any point on AD will be equidistant from AB and AC.
