©opyright 2005 Research Education Ltd and Primary ICT Solutions Well done You have got to the end of the quiz. Would you like to look back at the information sheets telling you about shapes?

©opyright 2005 Research Education Ltd and Primary ICT Solutions Correct There are five sides in a pentagon. A regular pentagon has internal angles of 72º. All shapes with five sides are pentagons.

©opyright 2005 Research Education Ltd and Primary ICT Solutions Correct A heptagon has 7 sides. The internal angles in a regular heptagon measure º. Although heptagons do not appear as often as hexagons, we do use them every day when buying things. A 50p is a heptagon.

©opyright 2005 Research Education Ltd and Primary ICT Solutions Correct A rectangle can be a square if all the sides are the same length, or an oblong if they are not. The internal angles in a rectangle are all 90º or right angles.

©opyright 2005 Research Education Ltd and Primary ICT Solutions Correct The pentagon is the odd one out as it has five sides. A trapezium is a four sided shape in which two of the sides are parallel and two are not. A rhombus is a four sided shape with two pairs of parallel sides and no right angles.

©opyright 2005 Research Education Ltd and Primary ICT Solutions Correct Just as an octopus has eight legs, an octagon has eight sides. October used to be the eighth month of the year until the calendar changed in 1752.

©opyright 2005 Research Education Ltd and Primary ICT Solutions Incorrect A quadrilateral has four sides – there are lots of four sided shapes including square, oblong, trapezium and rhombus. A hexagon has six sides.

©opyright 2005 Research Education Ltd and Primary ICT Solutions Incorrect A hexagon has six sides. An octagon has eight sides. There are eight notes in music. This is called an octachord. The most important of these is middle C.

©opyright 2005 Research Education Ltd and Primary ICT Solutions Incorrect A square is a form of rectangle. It is the only type of rectangle with four mirror lines. An oblong is a form of rectangle. An oblong only has two mirror lines.

©opyright 2005 Research Education Ltd and Primary ICT Solutions Incorrect Both a trapezium and a rhombus have four sides. An isosceles trapezium looks like a isosceles triangle with the top chopped off.

©opyright 2005 Research Education Ltd and Primary ICT Solutions Incorrect A six sided shape is called a hexagon. A ten sided shape is called a decagon. Dec often forms the start of words to do with ten. For example, decimal.
