Five common postulates of Euclidean geometry are:
• You can draw a straight-line segment from any given point to others.
• You can extend a straight-line to a finite length.
• It can be described as a circle with any given point as its center and any distance as its radius.
• In it all right angles are congruent.
• Lastly, if the straight-line intersect two other straight-lines, and make the two interior angles on one side of it together less than two right angles, then the other straight line will meet at a point on the side with less than two right angles.
