The shortest distance of a point is always the perpendicular distance.
The projection of the point (a,b,c) on the x-axis is (a,0,0).
This distance is given by b2+c2.

If a + b + c = 2s, then prove the following identities

(a) s2 + (s βˆ’ a)2 + (s βˆ’ b)2 + (s βˆ’ c)2 = a2 + b2 + c2

(b) a2 + b2 βˆ’ c2 + 2ab = 4s (s βˆ’ c)

(c) c2 + a2 βˆ’ b2 + 2ca = 4s (s βˆ’ b)

(d) a2 βˆ’ b2 βˆ’ c2 + 2ab = 4(s βˆ’ b) (s βˆ’ c)

(e) (2bc + a2 βˆ’ b2 βˆ’ c2) (2bc βˆ’ a2 + b2 + c2) = 16s (s βˆ’ a) (s βˆ’ b) (s βˆ’ c)
