In the following figure, AF is the perpendicular bisector of BD, AD = 20, and DF = 16. Find AB + BF.
Is the answer 36?
can't be that easy right?
This is how I did it:
A perpendicular bisector is the mid-line that cuts through a triangle.
If AD=20 then AB should also be 20 since they are identical.
DF=16 then BF should also equal to 16.
