This is not exactly a GeoGebra request...
btw have a look at triangles BDA and BAC. They are similar (same angles), so the corresponding sides are proportional, e.g.
BD/AB = AB/BC
Solve this for BD and it's done.
As per U sir it is RIGHT AB^2=BD.BC
(3)^2=BD(5)
9/5=BD
BD=1.8
DE=2.61.8=.7
BUT SIR IT IS FIVE LINE
I WANT IN SECONDS IN ONE LINE.
SIR recently a new theorem introduced ...........
