Letters that can form 1 or 2 polygons with an additional line segment typically include those with straight edges and closed shapes. For example, the letter "A" can be viewed as a triangle (polygon) with an extra line segment forming the crossbar. Similarly, the letter "H" can be seen as two rectangles (polygons) connected by a line segment. Other letters like "O" and "C" could also be adapted creatively to fit this criterion.
No, not necessarily. In theory you can assign different names to variables, and it doesn't always follow that they are alphabetical. So a divided by b could be x or t or n or any letter you like. Equally, you could use different letters in the initial calculation resulting in c, so x divided by y could be c. Having said that, letters used are commonly used in sequence, so a divided by b = c would be common. Having a, b and c together or x, y and z together is common. In certain situations though, certain letters are given special designations as in the famous E = mc² equation.

There are 5 letters: a c e f and h.If the letters can be repeated, then there are five possibilities for each space in the four-letter arrangement. The number of arrangements then is:5*5*5*5 = 54 = 625.
