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.
