Q. Which of the following sets of numbers could represent the three sides of a triangle?\newline{12,20,34} \{12,20,34\} \newline{4,6,11} \{4,6,11\} \newline{10,12,21} \{10,12,21\} \newline{13,18,33} \{13,18,33\}
  1. Recall Triangle Inequality Theorem: Recall the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
  2. Apply Theorem to Set {12,20,34}\{12, 20, 34\}: Apply the Triangle Inequality Theorem to the first set of numbers {12,20,34}\{12, 20, 34\}. Check if the sum of any two numbers is greater than the third number.12+20=3212 + 20 = 32, which is not greater than 3434.
  3. Set {12,20,34}\{12, 20, 34\} Analysis: Since 3232 is not greater than 3434, the set {12,20,34}\{12, 20, 34\} does not satisfy the Triangle Inequality Theorem and cannot represent the sides of a triangle.
  4. Apply Theorem to Set {4,6,11}\{4, 6, 11\}: Apply the Triangle Inequality Theorem to the second set of numbers {4,6,11}\{4, 6, 11\}. Check if the sum of any two numbers is greater than the third number.4+6=104 + 6 = 10, which is not greater than 1111.
  5. Set {4,6,11}\{4, 6, 11\} Analysis: Since 1010 is not greater than 1111, the set {4,6,11}\{4, 6, 11\} does not satisfy the Triangle Inequality Theorem and cannot represent the sides of a triangle.
  6. Apply Theorem to Set {10,12,21}\{10, 12, 21\}: Apply the Triangle Inequality Theorem to the third set of numbers {10,12,21}\{10, 12, 21\}. Check if the sum of any two numbers is greater than the third number.\newline10+12=2210 + 12 = 22, which is greater than 2121.
  7. Set {10,12,21}\{10, 12, 21\} Analysis: Check the other two combinations for the set {10,12,21}\{10, 12, 21\} to ensure all conditions of the Triangle Inequality Theorem are met.\newline10+21=3110 + 21 = 31, which is greater than 1212.\newline12+21=3312 + 21 = 33, which is greater than 1010.
  8. Apply Theorem to Set {13,18,33}\{13, 18, 33\}: Since all combinations of the set {10,12,21}\{10, 12, 21\} satisfy the Triangle Inequality Theorem, this set can represent the sides of a triangle.
  9. Set {13,18,33}\{13, 18, 33\} Analysis: Apply the Triangle Inequality Theorem to the fourth set of numbers {13,18,33}\{13, 18, 33\}. Check if the sum of any two numbers is greater than the third number.13+18=3113 + 18 = 31, which is not greater than 3333.
  10. Set {13,18,33}\{13, 18, 33\} Analysis: Apply the Triangle Inequality Theorem to the fourth set of numbers {13,18,33}\{13, 18, 33\}. Check if the sum of any two numbers is greater than the third number.13+18=3113 + 18 = 31, which is not greater than 3333.Since 3131 is not greater than 3333, the set {13,18,33}\{13, 18, 33\} does not satisfy the Triangle Inequality Theorem and cannot represent the sides of a triangle.
