which of the following are among the five basic postulates of euclidean geometry? check all that apply

d. any straight line segment can be extended indefinitely

Postulates or Axioms are universal truth statement , whereas theorem requires proof.

Out of four options given ,the following are basic postulates of euclidean geometry:

Option C: A straight line segment can be drawn between any two points.

u2192To draw a straight line segment either in space or in two dimensional plane you need only two points to determine a unique line segment.

Option D: any straight line segment can be extended indefinitely

u2192Yes ,a line segment has two end points, and you can extend it from any side to obtain a line or new line segment.

We need other geometrical instruments , apart from straightedge and compass to create any figure like, Protractor, Set Squares.

So, Option A is not Euclid Statement.

Option B , is a theorem,which is the angles of a triangle always add up to 180 degrees,not a Euclid axiom.

u2192Option C, and Option D

2. the answers are c and d

a straight line segment can be drawn between any two points

any straight line segment can be extended indefinitely
