Question

question 5
which of the following is not an axiom of geometry?
a straight line may be drawn between any two points.
any line segment can be extended to be a line.
all circles have the same radius and center.
all right angles are equal.

Explanation:

In geometry, axioms are fundamental statements. The statement "All circles have the same radius and center" is false as circles can have different radii and centers. The other statements are well - known geometric axioms. A straight line between two points, extension of line segments to lines, and equality of right angles are basic geometric concepts.

Answer:

C. All circles have the same radius and center.
