Question 1
Louis Braille developed his embossed dots for the visually impaired in 1824 when he was only 15 years old. The Braille cell is a 2 x 3 point block onto which raised dots are placed.
The figure shows the grid (small black dots) and the embossed arrangement (large red dots) to represent an exclamation mark (!). The center of symmetry is shown as an orange cross.
Study the Braille alphabet and determine how many letters have point symmetry 2 with respect to the center of symmetry.
