To determine whether a group of side measures will form a triangle, we can use the Triangle Inequality Theorem. According to this theorem, for a triangle with side lengths a, b, and c, the sum of the lengths of any two sides must be greater than the length of the third side.
Let's apply this theorem to each of the given groups of side measures:
1. Group: 12, 10, 22
The sum of 12 and 10 is 22, which is less than the third side measure of 22.
Therefore, this group of side measures will not form a triangle.
2. Group: 2, 7, 6
The sum of 2 and 6 is 8, which is less than the third side measure of 7.
Therefore, this group of side measures will not form a triangle.
3. Group: 8, 1, 7
The sum of 1 and 7 is 8, which is equal to the third side measure of 8.
Therefore, this group of side measures will not form a triangle as it violates the Triangle Inequality Theorem (the sum should be greater than the third side measure).
4. Group: 9, 4, 3
The sum of 4 and 3 is 7, which is greater than the third side measure of 9.
The sum of 9 and 3 is 12, which is greater than the third side measure of 4.
The sum of 9 and 4 is 13, which is greater than the third side measure of 3.
Therefore, this group of side measures will form a triangle as it satisfies the Triangle Inequality Theorem.
Based on the Triangle Inequality Theorem, the group of side measures that will form a triangle is 9, 4, 3.
