Q. Which of the following sets of numbers could represent the three sides of a triangle?{12,20,34}{13,25,38}{6,13,19}{15,24,36}
Understand Triangle Inequality Theorem: Identify 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.
Test First Set of Numbers: Test the first set of numbers {12,20,34} to see if they satisfy the Triangle Inequality Theorem.Check if 12 + 20 > 34, 12 + 34 > 20, and 20 + 34 > 12.12+20=32, which is not greater than 34.
First Set Does Not Satisfy Theorem: Since 12+20 is not greater than 34, the first set of numbers \{12,20,34\} does not satisfy the Triangle Inequality Theorem and cannot represent the sides of a triangle.
Test Second Set of Numbers: Test the second set of numbers 13,25,38 to see if they satisfy the Triangle Inequality Theorem.Check if 13 + 25 > 38, 13 + 38 > 25, and 25 + 38 > 13.13+25=38, which is not greater than 38.
Second Set Does Not Satisfy Theorem: Since 13+25 is not greater than 38, the second set of numbers \{13,25,38\} does not satisfy the Triangle Inequality Theorem and cannot represent the sides of a triangle.
Test Third Set of Numbers: Test the third set of numbers {6,13,19} to see if they satisfy the Triangle Inequality Theorem.Check if 6 + 13 > 19, 6 + 19 > 13, and 13 + 19 > 6.6+13=19, which is not greater than 19.
Third Set Does Not Satisfy Theorem: Since 6+13 is not greater than 19, the third set of numbers \{6,13,19\} does not satisfy the Triangle Inequality Theorem and cannot represent the sides of a triangle.
Test Fourth Set of Numbers: Test the fourth set of numbers {15,24,36} to see if they satisfy the Triangle Inequality Theorem.Check if 15 + 24 > 36, 15 + 36 > 24, and 24 + 36 > 15.15+24=39, which is greater than 36.15+36=51, which is greater than 24.24+36=60, which is greater than 15.
Fourth Set Satisfies Theorem: Since all the inequalities are satisfied for the fourth set of numbers {15,24,36}, this set does satisfy the Triangle Inequality Theorem and can represent the sides of a triangle.
