Question

in triangle ABC , AB=2.5,BC=3.4,AC=6,in triangle PQR,PQ=5,QR=1.7,PR=4.5 are this triangle similar or not ?explain.​

Answer 1

Answer:           no  , this triangle is not similar

Step-by-step explanation:

AB/PQ not= BC/QR

AB/PQ= 2.5/5

BC/QR=3.4/1.7

2.5/5 not= 3.4/1.7

1/2 not=2

Answer 2

Answer:

Answer:

Thus, we get PQ = , QR = 3 cm.

Step-by-step explanation:

We are given two similar triangles as \Delta ABC and \Delta PQR. (refer the figure attached)

Also, we know that;

Their corresponding sides would be equal in proportions. So we write as;

Since, we are given as;

AB = 6 cm, AC = 8 cm, BC = 4 cm, PR = 6 cm

Pick first and second, we get.

PQ = cm

Pick second and third, we get.

QR = 3 cm

Thus, we get PQ = , QR = 3 cm
