उत्तर
In ΔABC and ΔPQR,
`"AB"/"PQ" = 6/3 = 2/1` ......(i)
`"BC"/"QR" = 8/4 = 2/1` ......(ii)
`"AC"/"PR" = 10/5 = 2/1` ......(iii)
∴ `"AB"/"PQ" = "BC"/"QR" = "AC"/"PR"` ......[From (i), (ii) and (iii)]
∴ ΔABC ∼ ΔPQR ......[SSS test of similarity]
∴ The triangles in the figure are similar by SSS test of similarity.
