Answer:

2. Yes as 6 + 13 > 18

4. No as 29 + 9 = 38

6. Yes as 14 + 19 > 33

Explanation:

Triangle Inequality Theorem

The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Question 2

To determine if the given side lengths could form a triangle, sum the two shortest sides and observe if the sum is greater than the length of the longest side.

  • 6 + 13 > 18
  • 19 > 18

Therefore, as the sum of the shortest two sides is greater than the length of the longest side, the given side lengths can form a triangle.

Question 4

To determine if the given side lengths could form a triangle, sum the two shortest sides and observe if the sum is greater than the length of the longest side.

  • 29 + 9 = 38
  • 38 = 38

Therefore, as the sum of the shortest two sides is equal to the length of the longest side, the given side lengths cannot form a triangle.

Question 6

To determine if the given side lengths could form a triangle, sum the two shortest sides and observe if the sum is greater than the length of the longest side.

  • 14 + 19 > 31
  • 33 > 31

Therefore, as the sum of the shortest two sides is greater than the length of the longest side, the given side lengths can form a triangle.

Answer:

2) Yes, 4) No, 6) Yes

---------------------

Use triangle inequality theorem, according to which:

  • The sum of the smaller two side lengths must be greater than the longest side.

Q2)

  • 6 + 13 = 19 > 18, this is a yes

Q4)

  • 9 + 29 = 38, this is a no

Q6)

  • 14 + 19 = 33 > 31, this is a yes
