Part 1
How many lines of symmetry does a rhombus​ have?

Answer 1

A rhombus has **two lines of symmetry**. These lines of symmetry are as follows:

1. One line of symmetry runs diagonally from one vertex to the opposite vertex.
2. The other line of symmetry runs diagonally from the other pair of opposite vertices.

Lines of symmetry:
1. Line AC (from vertex A to vertex C)
2. Line BD (from vertex B to vertex D)
```

In the sketch above, the lines AC and BD represent the two lines of symmetry for the rhombus ABCD.
