There is a mirror M situated on the ground. Roshan is watching the reflection of the flag in the mirror. This condition is shown with the help of two triangles in the adjoining figure.If point P represents head of Roshan and point Q represents top of the pole (in which the flag is firling). We know with ( The help of law of reflection) ∠ PMG = ∠QMF.
