In a ` ABC ,` If `L and M` are points on `AB and A C` respectively such that `LM B Cdot` Prove that: `ar ( ABM)=ar ( ACL)`

Text Solution

Verified by Experts


`"Given"`
`In /_\ABC`
`"L is midpoint of AB"`
`"M is midpoint of AC"`
`"LM is parallel to BC"`
`therefore "the area of "/_\" on the same base and between the same parallel lines are equal "`
`here," LM and BC are parallel"`
`LM " is the common base"`
