Choose correct statements about reflection symmetry:

1. Point symmetry always exists in a figure having reflection symmetry.

2. Mirror symmetry is the same as reflection symmetry.

3. Line of symmetry always exists in reflection symmetry.

Reflection symmetry is a type of symmetry which is with respect to reflections. 

Reflection symmetry is also known as line symmetry or mirror symmetry. It 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.

So, Statement 2 and 3 are correct.
