Question

Consider ABCD (not a square). Which of these is true about its lines of symmetry?

It has four lines of symmetry: two diagonals and two medians

It has two lines of symmetry: the diagonal lines through the corners only

It has two lines of symmetry: the perpendicular bisectors of opposite sides (medians)

It has no lines of symmetry unless it is a square

Answer 1

I don’t have the picture you saw — can you upload it or describe the shape (are opposite sides parallel/equal, are angles right angles, are all sides equal)?

Here are the possibilities so you can match them to the image:

- Square: 4 lines of symmetry (both diagonals and the two mid‑line axes) — option 1.
- Rhombus (all sides equal, angles not 90°): 2 lines of symmetry — the diagonals — option 2.
- Rectangle (opposite sides equal, all angles 90°, not a square): 2 lines of symmetry — the perpendicular bisectors through midpoints (the medians/axes parallel to sides) — option 3.
- A general parallelogram that is neither a rectangle nor a rhombus has no lines of symmetry — option 4.

If you tell me which type ABCD is (or upload the image), I’ll pick the correct option.
