Geometry

Question Analysis:
The question asks about properties preserved in an isometry.

Key Concept Explanation:
Isometries maintain both shape and size, meaning figures remain congruent.

Step-by-Step Solution:
Check what an isometry preserves:
Shape stays the same. ✅
Size remains unchanged. ✅
Since both are preserved, C) Both shape and size is correct.

Option Analysis:
A) Shape only (Incorrect) – Size is also unchanged.
B) Size only (Incorrect) – Shape is also unchanged.
C) Bot...
