1) opposite sides are parallel to each other and will never intersect
2) opposite sides are equal in length
3) opposite angles are equal
4) any two adjacent angles add up to 180 degrees
5) can tessellate
6) has 2 lines of symmetry
7) may be a square, rectangle, rhombus or rhomboid
8) if you join the corners using lines ('x' in the centre), the 4 triangles formed will be equal and congruent to one another
9) any line that passes through the midpoint bisects the parallelogram
10) The diagonals (ie. the lines that join the corners) bisect each other
