Non-verbal communication is the process of conveying messages without using spoken words. It involves gestures, facial expressions, eye contact, body language, and tone of voice to express thoughts or emotions. It is crucial for understanding the feelings and attitudes of individuals during interactions.
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 \( BC = 3.6 \, \text{cm} \).
