A triangle `A B C` is right angled at `AdotA L` is drawn perpendicular to `B C` . Prove that `/_B A L=/_A C Bdot`

Text Solution

Verified by Experts

In traingle BAC and traingle BLC
`/_B=/_B`(common)
`/_BLA=/_BAC(90^@)`
and` BA=BA`(common side)
so from AAS RULE `/_\BAC cong/_\BLA`
from CPCT ,
` /_BAC=/_ACB`
