In one case the 1st square has an edge-length of 14 cm.
What is the edge-length of the 2nd square?
And the 3rd?
How many squares must be drawn until one has an edge less than 2 cm?
By looking at the sequence of edge-lengths,
can you see a simple relationship between them?
If so, then use that to determine the size of the 10th square to be drawn. © Frank Tapson 2004 [trolPT:10] T/6 T/7 Trigonometry

Drawings are NOT to scale. 1. Find the length of the space-diagonal of cuboid measuring 4 metres by 5 metres by 7 metres.
2. What is the greatest length of a thin rod, which must measure an exact number
of centimetres, and can fitted into a cuboidal box measuring 14 cm by 8 cm by 5 cm?
E 3. The drawing on the right represents a wooden wedge.
Face ABCD is in the horizontal plane, face ADEF is in
the vertical plane. BCEF is the sloping face.
BC is 10 cm; AB is 14 cm; AF is 4 cm.
If an insect set out to walk up the sloping face, starting
from C, i...
