Stress management is vital for maintaining mental and physical health. It helps in improving focus, productivity, and decision-making abilities. Proper stress management techniques, such as relaxation exercises, time management, and mindfulness, reduce anxiety and enhance overall well-being.
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 \( BC = 3.6 \, \text{cm} \).
