Question

if triangle ABC and triangle PQR are similar then find the length of PQ and QR .​

Answer 1

Step-by-step explanation:

1- The lengths of the both traingle is in ratio of 2:3.

2- AC= 12cm, and PR= 18 cm, (given)

similarly

since AB= 7cm, PQ= 10.5 cm. (for easiness, divide seven in two parts, which gives 3.5 cm, now since the ratio is 2:3, add 3.5 into 7, it gives 10.5 cm)

3- Similarly, for last side, divide 10 in half which is 5cm and now add 5 into 10 so it is 15 cm.

4- The final answer is PQ=10.5 cm and QR=15 cm

( Sorry for not giving formula but I tried to explain in simplest way)

Answer 2

Step-by-step explanation:

If triangle PQR is similar to ABC, then find "a"
