THIS USER ASKED 👇
Which graph shows a triangle and its reflection image over the x-axis
THIS IS THE BEST ANSWER 👇
C is the right choice
Step by step explanation:
Reflect over the x-axis and then represent that image over the y-axis
Some polygons have rotational symmetry, some have reflective symmetry. If you rotate an object about 180 degrees, or show it in a suitable axis, you will get the same shape back.
If you rotate a shape about 180 degrees, you get an upside-down shape, not a reflected shape.
Do the reflection in x-axis followed by the reflection in the y-axis. You will find that your new image will land on top of the original image.
Option d can only work if y = -x
