Question

P and Q are the points on sides AB and AC , respectively of ∆ABC .If AP=3cm ,PB=6cm,AQ=5cmand QC=10cm show that BC and 3PQ
​

Answer 1

Answer:

Step-by-step explanation:

AS IN THE FIGURE

In the triangles ABC and APQ

AP/AB =AQ/AC=3/(3+6)=5/(5+10)=1/3

Thus ΔABC and ΔAPQ are similar

Thus PQ/ BC=AP/AB=3/(3+6)=3/9=1/3

Thus BC=3PQ
