Euclid's first four postulates are:
- A straight line segment can be drawn joining any two points.
- Any straight line segment can be extended indefinitely in a straight line.
- Given any straight line segment, a circle can be drawn havibg the segment as radius and one endpoint as centre.
- All right angles are congruent.
He also had the fifth postulate, equivalent to the parallel postulate. There are various equivalent versions.
- 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.
The fifth postulate cannot be proven and, in fact, it is now known that it cannot be proven and that there are many internally-consistent geometries in which the negations of this postulate are true.
What else can I help you with?
What is postulate 8?
If two points are in a plane, then the line that contains the points is in that plane
What are points and lines in a plane?
Points and lines on the same plane are coplanar.
What are points or lines that are not in the same plane?
If the question is .. " Points and lines in the same plane "? then the anwser is COPLANER
Points that line on the same plane?
Points or lines that lie on the same plane are coplanar.
What is the line intersection postulate?
The line intersection postulate states that if two distinct lines intersect, they do so at exactly one point. This fundamental principle in geometry ensures that the intersection of lines is unique, meaning that no two lines can cross at more than one point. This postulate forms the basis for understanding the relationships between lines in a plane.

In a plane if two lines are perpendicular to the same line then they are parallel to each other?
Yes they are. It's a postulate: In a plane two lines perpendicular to the same line are parallel.

Can there be four points in one plane?
There can be any number of points on a plane, or even on a line - and any number of lines on a plane.
What do you call two or more points that lie on the same plane?
Points on the same plane are coplanar lines.
What is two lines in the same plane if they have no common points?
The lines are PARALLEL.
How many lines can be drawn out of 14 points on a plane with no 3 or more points collinear?
There are 91 lines.
Describe a point a line and plane?
points that lines in the same plane are coplanor
What is the flat plane postulate?
The flat plane Postulate, shows another way that one dimensional object relate to the two-dimensional plane.
