Each figure is made up of some identical squares. Which of the figure(s) has/have exactly 2 lines of symmetry?

1. Determine the number of lines of symmetry for Figure A

Figure A has rotational symmetry of order 2 but no lines of symmetry. Number of lines of symmetry = 0.

2. Determine the number of lines of symmetry for Figure B

Figure B is an I-shape. It has a vertical line of symmetry down the middle and a horizontal line of symmetry across the middle. Number of lines of symmetry = 2.

3. Determine the number of lines of symmetry for Figure C

Figure C is a square. A square has 4 lines of symmetry (vertical, horizontal, and two diagonals). Number of lines of symmetry = 4.

4. Select the correct option

Only Figure B has exactly 2 lines of symmetry. This corresponds to option (1).
