Give four figure grid reference of the triangular height 179 |
|
Answer» easiest way to REMEMBER this is to find the first number, WALKING down the HALLWAY (horizontal, x axis, east) and up the STAIRS (vertical, axis, NORTH). For example, the number 2 in the diagram below is 19 squares across and 45 squares at the top so, the four-digit grid reference is '1945'. |
