27. Next Page 1996 Mathematics Paper B Q11 Use a ruler to draw 2 more lines to make an isosceles triangle. Any isosceles triangle made by drawing two more lines, eg: (Isosceles = triangle with 2 sides the same length) Vertices need not be exactly on the dots provided intention is clear. There is no requirement to use the dots. Lines may go outside grid. Any triangle that uses the given line and has at least two sides equal to within 2mm is acceptable. Accept equilateral triangles.
