Kite or isosceles trapezium with only the given line of symmetry and no right angles
2
B1 for correct shape but inaccurate or • kite with right angle • arrowhead without right angle • rhombus
B0 for • square • rectangle • non-isosceles trapezium • arrowhead with right angle • parallelogram • triangle or shape with 5 or more sides
Mark intention: accept vertices \(\pm\) 2mm and freehand for 2 marks If in doubt, use overlay as guide. Place so the correct point would be in the centre of the square and their point must be in, or on, square formed by red lines within overlay Condone slight extensions, gaps and wobbles
If more than 1 drawing and no clear choice mark the worst
