Why doesn't ozone form as a 'triangle'?

O3 forms a bent shape, with two single bonds, each of which are double bonds half the time. Wouldn't each of them being connected in a triangle of single bonds be far more stable?

You would think right? But the problem comes in when you concider bond angles. To form a triangle the bonds would need to have an angle of 60° but according to VSEPR theory the bond angle on an atom with two bonding and two lone perfers to be at 104.5° (Edit: Note VSEPR is fairly simplistic but its in the right ballpark).  This creates a situation known as ring strain.  

Ring strain creates instability, and the amount of ring strain in cyclic ozone makes it very unlikely to form and remain stable.
