(Q2). Are the triangles similar ? If so, name the criterion of similarity. Write the similarity relation in symbolic form.

(i)

Solution :

( ∠G = ∠I alt. int. angles for the ∠F = ∠K parallel lines GF ∥ KI )

∠FHG = ∠IHK (Vertically opp. angle)

∴ △GHF and △IKH are similar by similarity rule. △GHF ~ △IKH.
