The triangle reflected across the y-axis. Does the reflected figure have 8 unit long? How you know
A, Yes, reflection preserves the orientation of the figure.
B, No, a reflected figure could be any size.
C, Yes reflection preserves the size of the figure.
D, No a reflected figure will be smaller than the original figure.
1 answer
The correct answer is:
C, Yes, reflection preserves the size of the figure.
Reflection across the y-axis is a transformation that changes the orientation of the figure but does not change its size. Therefore, the side length of the triangle remains 8 units long after the reflection.
