Which term best describes a mathematical statement of the form shown<br> below?<br> If A then B.
Mkey [24]
<h2>Conditional statement.</h2>

A mathematical statement of the form 'If A Then B' is a conditional statement.

<h3>Explanation:</h3>

A conditional statement in geometry is an if-then statement consisting of a hypothesis and a dependent conclusion.  The structure of a conditional statement is:

<em>If (......hypothesis......), then (......conclusion......)</em>

If  hypothesis = A and conclusion = B, the mathematical expression for a conditional statement is:  <u>A → B</u> and it is read as <u>If A then B.</u>

A conditional statement is always true unless the hypothesis is true and the conclusion is false.

A conditional statement can be written in form of its converse, inverse and contrapositive.

<u>Example of a conditional statement is</u>

A = I am 18 years old

B = I am an adult

A conditional statement is of the form (<u>A → B</u>) "If A then B"; therefore

If I am 18 years old, then I am an adult.
