#4.2A
recognise and give the names of polygons
To include parallelogram, rectangle, square, rhombus, trapezium, kite, pentagon, hexagon and octagon
#4.2B
understand and use the term ‘quadrilateral’ and the angle sum property of quadrilaterals
The four angles of a quadrilateral are \(90°\), \((x + 15)°\), \((x +25)°\) and \((x + 35)°\). Find the value of \(x\)
#4.2C
understand and use the properties of the parallelogram, rectangle, square, rhombus, trapezium and kite
#4.2D
understand the term ‘regular polygon’ and calculate interior and exterior angles of regular polygons
#4.2E
understand and use the angle sum of polygons
For a polygon with \(n\) sides, the sum of the interior angles is \((2n – 4)\) right angles
#4.2F
understand congruence as meaning the same shape and size
#4.2G
understand that two or more polygons with the same shape and size are said to be congruent to each other
