The formal definition of a polygon states that a polygon is a closed plane figure formed by _____ or more segments called sides.
Alona [7]
The answer would be three. The reasons are clear. You can't form a closed figure when you just have two sides. All they would do is just intersect each other. Also, one side must intersect with two other noncollinear sides. This means that a polygon has to have at least three sides.

What's the next number 2 7 8 3 12 9
puteri [66]

The <em>correct answer</em> is:

4.

Explanation:

Taking these numbers as groups of three, we have 2, 7, 8; 3, 12, 9.

In the first group, we can see that we first add 5 and then add 1.

The next group seems to start from the next consecutive number. That is, the first group starts with 2, and the next group starts with 3. The next terms in the second group are found by adding 5 to the second term of the first group (12 = 7+5) and then adding 1 to the third term of the first group (9=8+1); this is because we added 5 and added 1 previously.

Following this pattern, the next group of three would start from the next consecutive number up, 4. The next two terms would be 17 (12+5=17) and 10 (9+1=10).
