Y8 (10/2001)
a)

Uses the words scalene, equilateral, and isosceles to describe features of the castle including: 

  • the roof of the two towers (as equilateral triangles),
  • the flag (as an isosceles triangle), and
  • the door (2 scalene triangles).

equilateral - moderate
 
isosceles - difficult
 
scalene - difficult
b)

Uses the words circumference, diameter, and radius to describe features of the wheel(s) including:

  • circumference: distance around the rim/tyre/wheel.
  • radius (or half the diameter): distance of a wheel spoke.
  • diameter (or twice the radius): distance across the centre, distance of 2 spokes.

circumference - moderate
 
radius - moderate
 
diameter - difficult
