Activity:
-
Ask students to find ten complex numbers that have the same
absolute value. Use the length of 10 from the lesson page as an
example of the absolute value of complex numbers 8 + 6i, -8 + 6i, 8 - 6i,
-8 - 6i, 6 + 8i, -6 + 8i,
6 - 8i, -6 - 8i, 10i, -10i, 10, and -10.
Students' answers will vary.
-
Plot these numbers on a complex plane prepared on graph
paper.
-
Ask students to determine what geometric figure contains
ALL of the plotted points. A circle of
radius equal to the absolute value and center at the origin.
