Adduction movement refers to bringing a limb or body part closer to the body's midline. For example, moving an arm or leg inward toward the torso. It's the opposite of abduction, which moves limbs away from the midline.
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 \( BC = 3.6 \, \text{cm} \).
