A putter face must be flat so when you hit the ball it goes where you want it to go. If you are referring to loft, a putter has about 3-4 degrees of loft, this is because this loft gives the ball the most consistent roll.
Striking the ball squarely with the face of the putter is essential to holing the ball. However, you must know the lie of the green in order to determine your shot's direction.
There cannot be such a shape. It is not a cylinder because a cylinder sdoes not have a rectangular face. A rectangle must be a flat face and the only flat faces in a cylinder are the circle faces. The curved face can be "opened out" into a rectangular shape but because the face is curved it cannot be rectangular.
an irregular or regular shape. flat and no arcs. at least 3 sides a smiley face inside
Many references consider a face must be a flat surface, so a cylinder would fit this.
No it's not legal in tournament play. The putter is not allowed to resemble any other object. Also the the putter must have a greater distance measuring from the heal to toe than it does from front to back
Depends. There's nothing wrong with a club that looks sort of like a putter with loft. It can't, however, be usable from both sides. According to the rules: Appendix II, 4c states that: The clubhead must only have one striking face, except that a putter may have two such faces if their characteristics are the same, and they are opposite each other. This rule was intended to specifically prohibit clubs with two striking faces, but they made an exception for plain blade putters with two identical opposing faces.
I would say on flat ground due to the face that the poles must be kept straight in order to work well
Yes. If the putter has a split grip, both grips must be circular in cross section and at least 1.5 inches apart. The top grip must be at least 5 inches long. Otherwise, if one grip is used, the normal rules apply. (Rule 6)
2. One at the top and one at the bottom. The face that is cylindrical cannot be counted as a base because it is curved - in 3D shapes the base must be flat.
Each face of a polyhedron must be a polygon: a flat surface bounded by straight lines. So, if any of the faces is curved, the shape is not a polyhedron.
The Muslims must face holy Ka'abah while offering prayer.
Firstly, the number must be even. 2520 is perfectly divisible.
