The purpose of ICT is to facilitate the storage, retrieval, transmission, and sharing of information through technology. It enhances efficiency in communication, education, business, and daily life by integrating tools like computers, the internet, and digital communication devices.
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 \( BC = 3.6 \, \text{cm} \).
