2D
Shapes and Line Symmetry
After doing an elementary geometry investigating by making,
cutting and folding these regular 2D shapes, I found:







an
equilateral triangle has 3 internal angles and 3 lines
of symmetry.


a
square has 4 internal angles and 4 lines of symmetry.


a
regular pentagon has 5 internal angles
and 5 lines of symmetry.


a
regular hexagon has 6 internal angles
and 6 lines of symmetry.


a
regular octagon has 8 internal angles
and 8 lines of symmetry.

Is
there a pattern here? What is it?
Mind you... maybe I've got this completly wrong. Perhaps
you should fold the shapes for yourself to check the validity
of my findings.
