Answer:

Figure D. (A)

When you flip the figure across like a mirror, it remains the same shape as the other side. An easy way to determine this is by cutting a line down the middle.

Reflectional symmetry states that if there exists at least one line that divides a figure into two halves such that one-half is the mirror image of the other half.

Edit: Typo!

Figure C is the one that has reflective symmetry. It has a line of symmetry vertically down the middle, so the left side is a mirror image of the right side.

Reflective symmetry, also known as line symmetry, means that one half of the figure is a mirror image of the other half. You can determine if a figure has reflective symmetry by imagining a line through the figure and seeing if one side of the line is a mirror reflection of the other.

Looking at the four figures labelled A, B, C, and D:

- Figure A has an 'L' shape that does not appear to have a line of symmetry through it.

- Figure B has an arrow shape, which does not have reflective symmetry as the two halves are not mirror images of each other.

- Figure C has a triangular shape that appears to have a line of symmetry vertically down the middle, making the left half the mirror image of the right half.

- Figure D appears to be a flask or bottle shape that does not have reflective symmetry, as no line can divide it into mirror images.

Based on this visual inspection, Figure C is the one that has reflective symmetry. It has a line of symmetry vertically down the middle, so the left side is a mirror image of the right side.
