This triangle is isoceles.....the shortest angle bisector  will  be the one that bisescts angle "A"....it will be the altitude of the triangle


We can find the length of this bisector using the Pythagorean Theorem


Length  =   √ [ 14^2 -  13^2 ]   =  √ [196 - 169 ] =  √27  =  3√3 units


Here's a pic with AD, BE  and CF  being the bisectors.....as you can see,  AD  is the shortest bisector
