Download free 2d shapes worksheets (PDF), GCSE maths past paper questions and worked solutions for 2D shapes (1Q). This is a Grade 1 geometry topic from the GCSE questions by topic collection for Foundation and Higher tier GCSE Maths (Edexcel, AQA, OCR and IGCSE).
Know your polygons by their number of sides: Pentagon (5), Hexagon (6), Heptagon (7), Octagon (8), Nonagon (9), Decagon (10). A regular polygon has all sides equal and all interior angles equal, and a regular n-sided polygon has n lines of symmetry and rotational symmetry of order n.
For special quadrilaterals: a parallelogram has two pairs of parallel equal sides; a rhombus has 4 equal sides; a trapezium has exactly one pair of parallel sides; and a kite has two pairs of adjacent equal sides and 1 line of symmetry.
Example 1: Name the quadrilateral with: (a) 4 equal sides & 2 lines of symmetry (b) 1 pair of parallel sides.
Work out (a) (i) Write down the mathematical name of each of the shapes. (ii) Write down the order of rotational symmetry of shape **A**. (b) Add correct notation to the shape below to show that it is an isosceles triangle.

Worked Solution & Mark Scheme (3 marks)
Part (a) Solution:
Draw vertical and horizontal lines through the middle of the pattern M1 A1
Answer (a):Vertical and horizontal midlines
Part (b) Solution:
