State which pairs of triangles in Figure are similar. Write the similarity criterion used by you for answering the question and also write the pairs of similar triangles in the symbolic form:

Explanation

(i) In both thr triangles

Every angle is equal,

Thus, similar using AAA similarity.

(ii) in both the triangles,

Ratio of sides are equal,

hence, `(AB)/(QR)=(AC)/(QP)=(BC)/(RP)=1/2`

Hence, similar using SSS criterion.

(iii) In both the triangles,
