Answer:

Step-by-step explanation:

Another way to state it is to say that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. If you put the two shortest sides end to end, they have to be longer than the longest side to be able to angle up to form a triangle.

4. 1.1, 2.2, 3.2

5. 13, 5, 12

7. 5, 4, 3

8. 4, 4, 3

Step-by-step explanation:

In a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

1. 19, 16, 3

16 + 3 = 19

No triangle

2. 1, 2, 3

1 + 2 = 3

No triangle.

3. 3, 5, 7

3 + 5 = 8 > 7

3 + 7 = 10 > 5

7 + 5 = 12 > 3

Triangle

4. 1.1, 2.2, 3.2

1.1 + 2.2 = 3.3 > 3.2

2.2 + 3.2 = 5.4 > 1.1

1.1 + 3.2 = 4.3 > 2.2

Triangle

5. 13, 5, 12

13 + 5 = 18 >12

5 + 12 = 17 > 13

13 + 12 = 25 > 5

Triangle

6. 1, 7, 8

1 + 7 = 8

No triangle.

7. 5, 4, 3

5 + 4 = 9 > 3

4 + 3 = 7 > 5

5 + 3 = 8 > 4

Triangle.

8. 4, 4, 3

4 + 4 = 8 > 3

4 + 3 = 7 > 4

Triangle.
