conuturexample
it is called a conjecture
There is no conjecture about the sum of the first 30 positive even numbers. The answer can be derived and proven. A statement that has been proven is no longer a conjecture.
One possible conjecture is that it has one median which coincides with the corresponding altitude.
Conjecture: a statement which may or may not be true.Postulate: a statement that is believed to be true, but may not be.Theorem: a statement that has been proved to be true provided some postulates are true.Corollary: a statement whose truth follows from the truth of a theorem, but one which is not important enough to call it a theorem.
a conjecture
A counter example is a statement that shows conjecture is false.
conuturexample
it is called a conjecture
It is a conjecture, or an hypothesis in the scientific method. An hypothesis supported by experiment can become a theory.
Counter-example
There is no conjecture about the sum of the first 30 positive even numbers. The answer can be derived and proven. A statement that has been proven is no longer a conjecture.
(conjecture: a statement expressing an opinion based on incomplete evidence)"The report on possible terrorist plans was dismissed as mere conjecture.""The scientist would not conjecture on the effect the drilling might have on earthquake activity."
Find one counterexample to negate the statement
One possible conjecture is that it has one median which coincides with the corresponding altitude.
A statement that might be true (based on some research or reasoning), but is not proven. Like a hypothesis, but not stated in as formal, or testable, way. So a conjecture is like an educated guess. Example: I heard the sound of a plastic bag, so I conjecture there might be some food!
