In ΔABC, D is the midpoint of BC and G is the centroid of the triangle. If GD=2 cm, then the length of AD is:
In a triangle ABC, perpendicular AD from A on BC meets at D. If BD=8 cm, DC=2 cm and AD=4 cm, then ___.
A circle is inscribed in ΔABC touching the sides AB, BC and CA at points D, E and F respectively. If AB= 10 cm, BC = 12 cm and CA = 8 cm, then the lengths of AD, BE and CF respectively will be
