(a) perpendicular bisector
(b) angle bisector
(c) median
(d) altitude

answer:

there is no question attached to these aswer therforth no one will be able to aswer the problem

step-by-step explanation:

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

∠cbe and ∠deb are same-side interior angles.
