You don’t want to become sun-burned you put some more
sun lotion
onto your skin. You stroke the sun lotion with your fingers onto your sto-
mach and
paint
a “smiley” on it before you rub it into your skin.
Lying on the deckchair you get thirsty and imagine how wonderful a
pint
of lager
,
bitter or stout
would be. You can feel it run cold and refreshing
down your throat. A snack would be fine, too. What about some
crisps
?
They are a bit salty like the sea.
Hey, what’s that? A telephone is ringing. You can hear it very clearly. A
lady at some distance picks up a receiver. Quite strange. It’s not a mobi-
le phone. It’s an old fashioned telephone. That’s strange. She is talking
about
zodiac signs
. I can hear her say, „Yes, I’m a
Capricorn
.“
I stand up from my deckchair and want to walk over to her. I have to make
a giant step over my mess round my chair. There’s
suntan lotion
, a to-
wel,
crisps
on the
pebbles
. So I take this giant step to walk to this lady.
Someone is calling my name.
Guess who
? It’s a good friend of mine who
invites me to an interesting performance of a famous group at the theatre
tonight. I’m sure I am going to enjoy it.

Fundamentalkonstruktion zur Achsenspiegelung
Konstruiere zu zwei gegebenen Punkten P und Q die dazugehörige Sym-
metrieachse a.
Lösung: Nach Fundamentalsatz 8;3 sind nur Achsenpunkte von zwei zu-
einander symmetrischen Punkten P und Q gleich weit entfernt. Gleich
große Kreise um P und Q können sich demnach nur auf der Symmetrie-
achse zu P und Q schneiden. Wegen Fundamentalsatz l legt bereits ein
solches Kreispaar die gesuchte Achse eindeutig fest.
