Tobacco consumption increases the risk of lung cancer, heart disease, stroke, and respiratory issues. It damages the immune system, affects oral health, accelerates skin aging, and harms blood circulation. Secondhand smoke also poses health risks to non-smokers.
In the adjoining figure, \( AP = 1 \, \text{cm}, \ BP = 2 \, \text{cm}, \ AQ = 1.5 \, \text{cm}, \ AC = 4.5 \, \text{cm} \) Prove that \( \triangle APQ \sim \triangle ABC \).
Hence, find the length of \( PQ \), if \( BC = 3.6 \, \text{cm} \).
