Question

ABC is dilated to form AA''C'Which proportion can be used to determine the length of BC ?

Answer 1

Triangle ABC is dilated from A'B'C so we can get the proportion from These two triangles are

`(AC)/(A^(\prime)C^(\prime))=(BC)/(B^(\prime)C^(\prime))\Rightarrow(4)/(6)=(BC)/(8)`

Hence The correct anser is the first one which is

`(4)/(6)=(BC)/(8)`
