it was not until the end of the nineteenth century and the early part of the twentieth century and early part of the twentieth century after the foundations of geometry had been a=subjected to an intensive study that satisfactory postulate sets were supplied for Euclidean plane and solid geometry. Prominemt among such sets are those of O. Veblen D. Hilbert M. pieri and E.V. Huntington. Veblen's set contains 16 postulates and has point and order as primitive terms Hilbert's set contains 21 postulates and has point straight line plane n congruent and between as primitive terms Pieri's set contains 20 postulates and has point and motion as primitive terms Huntington's set contains 23 postulates and had sphere and inclusion as primitive terms
