Question

Use graph paper for this question. Take 1 cm = 1 unit on both axes.

i) Plot the points A (–2, 0), B (4, 0) and C (1, 4) on the graph.

ii) Plot D (–2, 4) and E (4, 4). Assign special name to quadrilateral ABED.

iii) Draw lines of symmetry of quadrilateral ABED, and DABC.

iv) Write the equation of lines of symmetry.

y = 2, x = 1
