A high velocity bullet will make an almost circular hole in a glass pane without much cracking. This can be measured easily even on small fragments of glass. [5], The shape of the hole formed by a projectile may also give information about the angle through which the force was delivered. If a bullet strikes the glass at right angle to the surface, there will be equally distribution of glass chipping on the opposite side and leaving a symmetrical hole. If a bullet strikes the glass from the left side of the surface, there will be chipping around the right side of the exit surface and forming an elliptical hole. Matching areas can.
