(a) Find the perimeter and area of rectilinear shapes.
(b) Find the area of a triangle, trapezium, parallelogram.
(c) Find the area and circumference/perimeter of circles and fractions of circles (e.g. 1/2, 1/4).
(d) Appreciate strategies to find areas of composite shapes, by (i) adding areas (ii) subtracting areas, including appreciation of the 'frame' method and (iii) cutting/reforming areas.
(e) Appreciate that triangles have the same area if their base and height are the same, and compare sizes of triangles by considering the proportion of base/height.
(f) Find what fraction of a shape is shaded by splitting into congruent shapes.
Covers geometric problems (involving lengths, angles and area) found in Intermediate Maths Challenges and Olympiads.
Used for Tiffin Year 9 scheme of work. Find the lengths of arcs and the area of sectors (does not cover segment areas).
