if you are doing proof statements...there is converse which is where you flip the statement around so if the statement would be IF a angle measures 90 degrees, THEN the angle is a right anlge. The converse would be IF a angle is a right angle, THEN it is 90 degress. THE COUNTEREXAMPLE would be if the statement was false you would say or show a picture of something defining that statement

What does counter example mean in math terms?
It is an example that demonstrates, by its very existence, that an assertion is false. Usually experience suggests that the assertion is true: there is a large amount of supporting "evidence" but the statement has not been proven. The counter-example, though demolishes the assertion For example: Assertion: all prime numbers are odd. Counter example: 2. It is a prime but it is not odd. Therefore the assertion is false. This was a favourite "trap" at GCSE exams in the UK. Assertion: if you divide a nuber it becomes smaller. Counter example 1: 2 divided by a half is, in fact, 4. Counter example 2: -10 divided by 2 is -5 (which is larger by being less negative).
