6 Geometry
The 12 sets of basic geometry problems in this section involve lines, angles, triangles, rectangles, squares, and circles. For example, you may be asked to find the area or perimeter of a shape, the length of a line, or the circumference of a circle. In addition, the word problems
will illustrate how closely geometry is related to the real world and to everyday life.
