16. A method of making a cutting element for an earth-boring tool, comprising:
forming first faceted surfaces in a transition region extending from proximate to a periphery of the cutting element radially inward and axially toward a rotationally leading end of the cutting element and to a cutting edge defined at an intersection of the transition region with a cutting face at the rotationally leading end, a perimeter of the cutting edge defining a polygonal shape, each first faceted surface extending at a first angle relative to a central geometric axis of the cutting element, the rotationally leading end positioned and configured to engage with, and remove, a material of an earth formation, a number of the first faceted surfaces being equal to a number of sides of the polygonal shape; and
forming second faceted surfaces in the transition region, each second faceted surface extending at a second, different angle relative to the central geometric axis of the cutting element, the first faceted surfaces and the second faceted surfaces intersecting one another at edges around a periphery of the transition region, a number of the second faceted surfaces being equal to a number of nodes of the polygonal shape.
