TO-DETERMINE if the given side lengths form a
Answer to Problem 26E
Option C forms a triangle using the triangle inequality theorem.
Explanation of Solution
Given information:
The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.
Three options are given along with their sides-
a.
Calculation:
As per the theorem,
Now check for all the three options given
Option a-
Let
Now add and check-
So, option a cannot form a triangle using the inequality theorem.
Option b-
Let
Now add and check-
So , option b cannot form a triangle using the inequality theorem.
Option c-
Let
Now add and check-
Now with the other two equations as well
Now add and check-
Now add and check-
So, option c fulfills the inequality theorem.
Conclusion- Since option c fulfils the sum of the lengths of any two sides of a triangle which is greater than the length of the third side.
Hence, option c forms a triangle using inequality theorem.
