Final answer:
To order the sides of a triangle from shortest to longest, compare their lengths.
Step-by-step explanation:
The sides of a triangle can be ordered from shortest to longest by comparing their lengths. Let's look at the options:
In option A, KL is the shortest, followed by JK, and then JL. So, the correct order is KL, JK, JL. In option B, JK is the shortest, followed by KL, and then IL.
In option C, JL is the shortest, followed by KL, and then JK. In option D, KL is the shortest, followed by IT, and then IK. Therefore, option A, KL, JK, JL, is the correct answer.
