Reflective Symmetry (b)

THINGS TO DO

You should have two acute and two obtuse Isotiles.

Look very carefully at the parallelogram. Is the line where the two Isotiles meet a line of reflective symmetry? Lift the Isotiles up as you did with the rhombus. Do they meet exactly?

What about the pentagon? How many lines of reflective symmetry does it have and where are they?
