Bond order is simply defined as no of bonds between  two atoms. for ex: co2 has two Bond order as 0=c=0 is the molecular structure.  There is simple relation which you can understand  as more no of Bond between  any two atoms that means they are more closer to each other, so for breaking of Bond it will require  more energy  as compare to single Bond.  Hence from  this discussion  we get  thatBond order is directly proportional to bond energy &inversly proportional  to bond length
						

							There is a simple relation between  Bond order & bond length. But if we talk about Bond angle then  Bond angle depends on Hybridisation of atom &hybridization also varies with no of bonds  formed  by atom There is no any direct relation between  bo&ba
						

							Bond Length : Internuclear Distance b/w two atoms in a molecule is called Bond Length.                                                     Stability is inversely proportional to Bond Length  Bond Angle   :  The angle formed b/w orbitals having bonded pair of e- to a central atom ina a molecule is called Bond Angle.Bond dissociation energy​   :  The energy required to break down a bond b/w two atom in a molecule is called Bond dissociation energy​ ​                                Stability is directly proportional to Bond dissociation energy​ ​  ​
