Question

if △ ABC ~ △A'B'C' and AC=20cm,A'C'=15cm,B'C'=12cm andA'B'=9cm find the lengths of the other sides of △ABC.​

Answer 1

Answer:

AB=12    BC=9

Step-by-step explanation:

Any side of a triangle must be shorter than the other two sides added together.

AB and A'B' must measure LESS than  the other 2 sides

  15 is 3/4 of 20

   12 is 3/4 0f 9

 

20/15   12/9    = 1.3333333........
