Students use their knowledge of vertically opposite angles, adjacent angles on a straight line, and angles at a point to identify unknown angles in everyday shapes.
For this task students are required to record, in a table, the compass bearings of objects shown on a submarine radar screen. Distances from the submarine are also recorded.
The context for this task is a grid-referenced map of historical sites. Students locate items at three grid references then write the grid references for all the castles on the map.
