Suppose point C is at (–1, –1). Use the numbers below to explain the distance that a fourth point, D, should be from the existing points to form a square. Numbers may be used once, more than once, or not at all.
–112–11211122
A and B are
units apart. A and C are
units apart. So the fourth point should be
units to the left of point B and
units above point C.
