Euclid's Postulates 1. A straight line segment can be drawn joining any two points...... 2. Any straight line segment can be extended indefinitely in a straight line....... 3. Given any straight line segment, a circle can be drawn having the segment as radius and one endpoint as center....... 4. All right angles are congruent....... 5. If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two lines inevitably must intersect each other on that side if extended far enough. This postulate is equivalent to what is known as the parallel postulate.......... I hope it helps

Postulate 1:a straight line may be drawn from any point to any other point. postulate 2:a terminated line can be produced indefinitely. postulate 3:a circle can be drawn with any centre and any radius. postulate 4:all right angles are equal to one another. postulate 5:2distinct intersecting line cannot be parallel to the same line.
