Given that ABCD is a trapezium such that AD//BC.
The centroid of △ABD lies on the bisector of ∠BCD.
Show that the centroid of △ABC lies on the bisector of ∠ADC.
Given an isosceles triangle ABC
which ∠A= 30°, AB = AC.
A point D is midpoint of BC .
A point P is chosen on then
segment AD and a point Q is
chosen on the side AB so that
BP= PQ.
Find the angle PQC
