40 revision cards testing understanding of Argand diagrams. One one side of the card is a complex loci, such as |z - (3 + 2i)|>4 and on the other side is a graph of the loci.
Cards can be printed double sided if you either have a duplexing printer or the patience to reload the sheets.
Alternatively, print them single sided and use them as a matching card game.
Questions include questions such as:
|z| = number, |z| > number, |z| < number, as well as |z - (x + iy)| situatons
arg (z) = angle, arg (z) > angle, arg (z) < angle as well as arg (z - (x + iy)) situations
Circles intersecting lines and circles intersecting circles.
Perpendicular bisectors |z-(x + iy)| = |z - (a + ib)|
