\"similar<\/p>\n

Solution :<\/h2>\n

(i)<\/strong>\u00a0 In triangles ABC and PQR, we observe that<\/p>\n

\\(\\angle\\) A = \\(\\angle\\) B = 60,<\/p>\n

\\(\\angle\\) P = \\(\\angle\\) Q = 80<\/p>\n

and \\(\\angle\\) C = \\(\\angle\\) R = 40<\/p>\n

\\(\\therefore\\)\u00a0 By AAA criterion of similarity, \\(\\triangle\\) ABC ~ \\(\\triangle\\) PQR<\/strong><\/p>\n

(ii)<\/strong>\u00a0 In triangles ABC and PQR, we observe that<\/p>\n

\\(AB\\over QR\\) = \\(BC\\over RP\\) = \\(CA\\over PQ\\) = \\(1\\over 2\\)<\/p>\n

\\(\\therefore\\)\u00a0 By SSS criterion of similarity, \\(\\triangle\\) ABC ~ \\(\\triangle\\) PQR<\/strong><\/p>\n

(iii)<\/strong>\u00a0 In triangles LMP and DEF, we observe that the ratio of the sides of these triangles are not equal.<\/p>\n

So, the two triangles are not similar.<\/strong><\/p>\n

(iv)<\/strong>\u00a0 In triangles MNL and QPR, we observe that \\(\\angle\\) M = \\(\\angle\\) Q = 70<\/p>\n

But, \\(MN\\over PQ\\) \\(\\ne\\) \\(ML\\over PR\\)<\/p>\n

So, these\u00a0two triangles are not similar<\/strong>\u00a0as they do not satisfy the SAS criterion for similarity.<\/p>\n

(v)<\/strong>\u00a0 In triangles ABC and FDE, we observe that \\(\\angle\\) A = \\(\\angle\\) F = 80<\/p>\n

But, \\(AB\\over DE\\) \\(\\ne\\) \\(AC\\over DF\\)<\/p>\n

So, these two triangles are not similar<\/strong> as they do not satisfy the SAS criterion for similarity.<\/p>\n

(vi)<\/strong>\u00a0 In triangles DEF and PQR, we observe that<\/p>\n

\\(\\angle\\) D = \\(\\angle\\) P = 70,<\/p>\n

\\(\\angle\\) E = \\(\\angle\\) Q = 80<\/p>\n

\\(\\therefore\\)\u00a0 By AAA criterion of similarity, \\(\\triangle\\) DEF ~ \\(\\triangle\\) PQR<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
