Hexagons
THINGS TO DO
You should have two acute and two obtuse Isotiles.
On the left is a regular hexagon: six equal sides and six equal angles.
Can you put all four Isotiles together, so that you also make a hexagon? It will have equal sides but not equal angles, so although it will look almost the same shape, it will not be strictly a regular hexagon.
Work out the sum of all six angles of this shape, by adding together all the angles of the Isotiles.
