In plane geometry, complex numbers can be used to represent points, and thus other geometric objects as well such as lines, circles, and polygons. Intuitively, a space is expected to possess a kind of arrangement or order that is not required of a set. You can focus on plane geometry by using pattern blocks in place of the geometric solids and modifying the sorting activities accordingly.

In a threedimensional space, a plane can be defined by three points it contains, as long as those points are not on the same line. In a coordinate plane, two nonvertical lines are perpendicular iff the product of their slopes is 1. For each pair of triangles, determine whether adding one more pair of congruent angles or sides would lead to congruent triangles. The distances from a point m to the vertices a, b, and c of a triangle are equal to 1, 2, and 3, respectively, and from a point m 1 to the same vertices to 3, 15, 5, respectively. It can be extended indefinitely in both directions.
