Question

in triangle PQR PQ=8cm OR=12cm PR=10cm if triangle PQR ~triangle ABC and AB=12cm find length of remaining sides of triangle ABC plz give answers of my question plz ​

Answer 1

Answer: If both the triangles are congruent so the remaining sides of triangle ABC will be same as triangle PQR i.e. 8cm and 10cm.

Answer 2

Answer:

bc=18 cm and ca=15 cm

Step-by-step explanation:

In similar triangles:

ar(pqr)/ar(abc)=pq^2/ab^2=qr^2/bc^2=rp^2/ca^2

so, (8/12)^2=qr^2/bc^2=rp^2/ca^2

root on all sides gives us,

2/3=12/bc=10/ca      -(1)

so, from eq.(1) bc=18 cm

                        ca=15 cm
