Question Analysis
This question focuses on the concept of ratios in similar shapes. The main task is to determine the ratio of corresponding side lengths between two similar triangles using the given lengths of a pair of corresponding sides.
Key Concept Explanation
For similar triangles, the ratio of corresponding side lengths is constant. If we have two similar triangles and is the length of a side in one triangle, and is the length of the corresponding side in the other triangle, the ratio of corresponding sides is expressed as or .
Step - by - Step Solution
1. We are given that one side length cm in one triangle and the corresponding side length cm in the other triangle.
2. To find the ratio of corresponding sides, we write the ratio as . Substituting the given values, we get .
3. Simplify the ratio by dividing both numbers by their greatest common divisor, which is 14. So,
