CSEC Mathematics · January 2014 · Paper 2 · Question 8(a)

The diagram below shows the first three figures in a sequence of figures. Each figure is made up of one or more trapezia with dots one unit apart on their parallel sides. Each trapezium can be partitioned into four congruent triangles.

On the answer sheet provided, draw Figure 4, the FOURTH figure in the sequence.

This question uses a figure or table from the paper — you'll see it when you practise.
