Thus, the postulates of Euclid were as follows: that a straight line may be drawn between any two points; that any terminated straight line may be produced indefinitely; that about any point as a center a circle with any radius may be described; that all right angles are equal; that if two straight lines lying in a plane are met by another line, making the sum of the internal angles on one side less than two right angles, then those straight lines will meet, if sufficiently produced, on the side on which the sum of the angles is less than two right angles. See axiom.
    • n postulate A self-evident practical proposition, to the effect that something is possible: opposed to an axiom, as a self-evident proposition that something is impossible. The fourth and fifth of Euclid's postulates (see def. 2) being converted into axioms in the modern editions, and his proved propositions being distinguished into theorems and problems, this new conception of a postulate naturally arose.
