New Letts Maths Paper C Q28 Angle in Reg Hexagon
Posted: Mon Aug 30, 2010 2:41 pm
Q28: This is a regular hexagon. What is the size of angle x in the shape?
(X is one of the six interior angles) I know that the interior angles are equal in a regular polygon and that the sum of the interior angles in a hexagon is 720 so the answer is 120. But is this a Y6 question? I don't see this anywhere in the KS2 revision guide. My elder dd who is Level 6 maths and did nine entrance exams last year could not do this question and has never seen a question like this before. Has anyone seen a question like this on any other paper? Do I need to start teaching younger dd all about interior and exterior angles in more than just triangles and quadrilaterals at KS2 level?
