To describe: The scale factor of two congruent

Answer to Problem 27HP
As the ratios of all corresponding sides of two congruent triangles are 1, so it’s required scale factor of two congruent triangles is 1.
Explanation of Solution
Given information:
Any two congruent triangles, say
Concept used:
The scale factor between two figures is the same ratio of their corresponding sides. And in congruent triangles, the corresponding sides pairs are always equal.
Calculation:
So, in two said congruent triangles
Required scale factor of two such triangles
Conclusion: Thus, the scale factor of two congruent triangles is 1 always.
