Answer:
D
Step-by-step explanation:
This is because when making a triangle, the two shortest sides have to add up to be bigger than the biggest side. For example, A would work because if you did 4+6, it would equal 10 which is bigger than the biggest side. B and C add up to something bigger than 6. However, D is different. If you do 2+4, that equals 6. It has to be bigger than six, not equal
The <em><u>correct answers</u></em> are:
A-theorem
; B-corollary
; C-Postulate
; and E-Definition.
Explanation:
In a proof, we are tasked with proving one statement using other information that has already been proven.
Theorems are statements that have already been proven, and are used to prove other statements.
A postulate is a statement that is assumed to be true, and is used to prove other statements.
A corollary is a direct consequence of a proven fact, and as such, are used to prove other statements.
A definition is an absolute truth, so it can also be used to prove another statement.

Answer:
The number 9 is greater than 1 and less than 10, while its factors are 1, 3 and 9, therefore it is a counter example to the statement.
Step-by-step explanation:
There are four odd numbers between 1 and 10, they are: 3, 5, 7 and 9. Let's check the factors for each of them.
For 3:
Therefore 3 is not a counter example to the statement, because it behaves as stated.
For 5:
Therefore 5 is not a counter example to the statement, because it behaves as stated.
For 7:
Therefore 7 is not a counter example to the statement, because it behaves as stated.
For 9:
Therefore 9 is a counter example to the statement, since it can be divided by 1, 3 and 9.
