Question
In fig, seg DE || sec BC, identify the correct statement.
Options
`"AD"/"DB" = "AE"/"AC"`
`"AD"/"DB" = "AB"/"AC"`
`"AD"/"DB" = "EC"/"AC"`
`"AD"/"DB" = "AE"/"EC"`
Solution
`"AD"/"DB" = "AE"/"EC"`
Explanation:
In ΔABC,
seg DE || sec BC ...(Given)
∴ By Basic proportionality theorem,
`"AD"/"DB" = "AE"/"EC"`.
