- Compass points
- Angular bearings
What is another name for compass points?
Compass direction
What is another name for angular bearings?
Compass bearings
What instrument is used for telling direction?
Compass
State the angular bearings for the following 8 point compass points:
-N
-NE
-E
-SE
-S
-SW
-W
-NW
-N = 0° / 360°
-NE = 45°
-E = 90°
-SE = 135°
-S = 180°
-SW = 225°
-W = 270°
-NW = 315°
Give the range of bearings values for the following 16 point compass directions:
-NNE
-ENE
-ESE
-SSE
-SSW
-WSW
-WNW
-NNW
-NNE = 1° - 44°
-ENE = 46° - 89°
-ESE = 91° - 134°
-SSE = 136° - 179°
-SSW = 181° - 224°
-WSW = 226° - 269°
-WNW = 271° - 314°
-NNW = 316° - 359°
What are eastings and northings ?
Eastings- vertical lines that move from north to south and increase in number moving in an easterly direction.
Northings- horizontal lines that move from east to west and increase in number in a northerly direction.

What is a map?
A plan or view from above
Describe large scale maps.
-A lot of detail
-small area of land(small number)
- shows landmarks, beaches streets etc
Describe a small scale map.
- little detail
- large area(big number)
- shows countries regions etc
Explain enlarging and reducing a map.
To get new size of square- add or subtract percentage or amount it asks you to and multiply that by however much the side of the square is now.
To get new scale-
Enlarging: divide the original number by the new percentage.
Reducing: multiply denominator by reduced percent then divide by it flipping the fraction.
Note: the scale is always 1 to something
