Write the following statement as a conditional statement.

stars have ten vertices.

a) if a figure has ten vertices, then it is a star.

b) a figure is a star, if and only if, it has ten vertices.

c) star are figures with ten vertices.

d) if a figure is a star, then it has ten vertices.

The correct option is D.

Step-by-step explanation:

The given statement is "Stars have ten vertices".

If a complete statement has two sub statements p and q, then the conditional statement is "If p, then q", where p is a hypothesis and q is a conclusion.

In the given statement,

p = A figure is a star.

q = It has ten vertices

So, the conditional statement of the given statement is

If a figure is a star, then it has ten vertices.

Therefore the correct option is D.
