Which diagram has all the correct lines of reflectional symmetry for the rectangle?

The correct answer is:

The second diagram.

Explanation:

The lines of reflectional symmetry are the lines through which the figure can be folded exactly in half.

A rectangle can be folded in half both vertically through the middle and horizontally through the middle. However, folding a rectangle through its diagram will not fold it exactly in half; one part will overlap the other, they will not meet exactly.

This means the only lines of reflectional symmetry should be horizontally through the center and vertically through the center.

The 2nd one

Step-by-step explanation:

Lines of reflectional symmetry-lines that allow the figure to be folded in half

In this instance, the second image is correcct because a rectangle can be folded in half both vertically and horizontally. However, folding a rectangle in the "X" shape, so to speak, will not fold it exactly in half. One part will overlap the other. Since the second one is the only one that doesn't do that, it's the right answer

Hope this helps :)
