GERI FROM LONDON said:
But how do I accurately draw an angle, say 15 degrees? I know it can be done
by geometry using the relative lengths of the adjacent and opposite sides in
a right angle triangle; but that works only for right angled triangles -
geometric tables are needed. So can you further advise?
.... Graham's is very very busy ... watching Neighbours ...
what you are describing is a tangent ...
in the win' calculator type fifteen ...
press the tan button and note the value ...
you've your adjacent and opposite sides ...
tan 15 = 0.267...
which is approximately one quarter ...
a going of four ... a rising of one ...

angle = 15 | height = 1

length = 4
PS. I know I repeated the word 'very' in the first line,
but you try writing ten syllables per line. Pffft ...
