Question

if triangle abc is similar to triangle pqr, ab=5cm, bc=2cm and pq=3cm, then qr is what percentage of bc?​

Answer 1

when two traingles are similar , ratio of their corresponding sides is equal.

ab/pq = bc/qr = ca/rp

so ,

5/3 = 2/qr

qr = 2 / ( 3/5)

qr = 10/3

qr = 3.33 cm .

as ,

bc = 2 & qr = 3.33

qr is( 3.33/2 × 100 ) % of bc

so , qr is 166.6 % of bc .
