If the flag is enlarged by scale factor
and then by scale factor
, how large will it be at the end? Will it have changed
the way it is facing?
You might find it useful to use vectors for the proof at the end of this
question. For example, you could write
for the vector from
the first centre of enlargement to the second centre of enlargement,
and
for the vector from the first centre of enlargement to
the foot of the flagpole. If you can prove your answer for the foot of
the flagpole, do you need to do any extra work to prove it for the rest of
the flag?
