1. Draw a convex quadrilateral that has no right angles, no parallel sides and no equal sides. Label the 4 corners of your quadrilateral a, b, c, and d. Trace and cut out 11 more identical quadrilaterals and label the angles. Put the quadrilaterals together so they tessellate, and the pattern you're using to tessellate is clear from your example (it's easy to see how the pattern would continue so you could cover the whole plane in the same way. Tape your tessellation together and turn it in Friday or take a picture of it and send it to me by Friday.

2. Do the same thing with a concave quadrilateral (with no right angles or parallel or equal sides).

3. Do the same thing with an obtuse scalene triangle.
