Hence, ∠BMN + ∠DNM = 180° => 1/2∠BMN + 1/2∠DNM = 90° => ∠PMN + ∠PNM = 90° => ∠1 + ∠2 = 90° ............. (i) In △PMN, we have ∠1 + ∠2 + ∠3 = 180° ......... (ii) From (i) and (ii), we have 90° + ∠3 = 180° => ∠3 = 90° => PM and PN intersect at right angles.

here you go and if u want more solutions just dm me
