Hint 2 of 2
Mirroring side-to-side and then top-to-bottom leaves the shape looking turned upside down.
Show solution
Approach: copy the same two mirror steps onto the 5
- Watch the 4: the first mirror flips it left-right, the second mirror flips it top-to-bottom.
- Doing both flips in a row is the same as turning the figure halfway around (upside down).
- Turn the 5 upside down the same way, and it matches choice C.
