Consider the following statements regarding 2D transforms in computer graphics:
S1: \(\left[ {\begin{array}{*{20}{c}} 1&0\\ 0&{ - 1} \end{array}} \right]\) is a 2 × 2 matrix that reflects (mirrors) only 2D point about the X-axis.
S2: A 2 × 2 matrix which mirrors any 2D point about the X-axis, is a rotation matrix.
What can you say about the statement S1 and S2?1
Both S1 and S2 are true
2
Only S1 is true
3
Only S2 is true
4
Both S1 and S2 are false
