|G1.2 Understand and use the angle properties of parallel and intersecting lines. Understand and use the angle properties of triangles.                                                                   |
|G3.6 Understand and use bearings.                                                                                                                                                                       |
|G4.1 & G4.1h Calculate perimeters and areas of shapes made from rectangles and triangles and extend to other compound shapes.                                                                           |
|G4.3 Calculate areas and circumferences of circles.                                                                                                                                                     |
|Key terms: vertically opposite, parallel, transversal, alternate angle, corresponding angle, interior (allied) angles, bearing, base, perpendicular height.                                             |
|Prior knowledge needed: the terms clockwise and anticlockwise; how to distinguish between acute, obtuse, reflex and right angles; that angles at a point add up to 360°; that angles on a straight line |
|add up to 180°; that vertically opposite angles are equal; that angles in a triangle add up to 180°; how to find the perimeter and area of rectangles; the definition of a parallelogram and a           |
|trapezium; the names of basic parts of a circle: centre, diameter, radius and circumference....
