If the incircle of â–³ABC touches the sides AB,BC and CA at P,Q and R, find the value of :
Question 58 (h)
Subtract:
2(ab + bc + ca) from -ab - bc - ca.
In the given figure, the incircle of △ABC touches the sides AB, BC and CA at the points P, Q, R respectively. Show that AP+BQ+CR=BP+CQ+AR =12 (Perimeter of △ABC) [3 MARKS]
In triangle ABC prove AB+BC+CA >2AB
