The total of the numbers inside the T-shape is 1+2+3+11+20=37. This is called the T-total. The number at the bottom of the T-shape is called the T-number. The T-number for this T-shape is 20. Part 1: Investigate the relationship between the T-total and the T-number We can investigate the relationship between the T-total and the T-number by translating the T shape several times and by looking at how this affects the values of T-number and T-total. A translation moves every point of the shape the same distance and direction. A translation is described by a vector in the form of (a,b) where the value of a shows how many spaces the shape moves horizontally. If the value of a is positive the shape moves to the right and if the value of a is negative the shape...
