You may, for example, need to apply the Pythagorean theorem, or you may need to calculate the perimeter of a figure. At this point, you need to apply what you've learned to analyze the figure and other data to solve the problem. Use this step to fill in as much missing information in your diagram as you can.ħ. Perhaps you can show two triangles to be congruent or similar, or perhaps you can identify congruent segments or angles. This step can greatly simplify the problem. Identify any appropriate geometric relationships. If your diagram is a composite figure, it may help to divide the figure into bite-sized portions that you can handle.Ħ.
Divide the figure, if necessary, into manageable portions. If no units are given, simply use the generic term "units" in place of inches or meters, for example.ĥ. Using units of square meters for a length or angle measure can be an embarrassing mistake! Keep careful track of the units you are using throughout the problem. In either case, record them and mark them in some manner on your diagram.Ĥ. If you are calculating an area, for instance, you may need to take measurements of certain lengths (alternatively, these may be provided to you). Even if you only use a rough sketch, however, making a visual representation of the problem can help you organize your thoughts and keep track of important information such as the relationship of line segments and angles as well as the measures thereof.ģ. Sometimes a straightedge, compass, protractor, or some combination of these tools can be helpful. If you are conscious throughout the process of what you need to determine, you can save yourself a significant amount of time.Ģ. In some cases, you may need a length in others, an area or angle measure. Determine what you need to calculate to solve the problem. This approach is similar to that for solving almost a word problem, but is geared slightly more toward the characteristics of geometry problems in particular.ġ. It behooves us to present a basic approach to solving practical geometry problems.
Some measurements of the building might, of course, be required, but the same problem-solving techniques apply.

For instance, you already know how to calculate the area of a composite figure if you were asked to determine how much floor space is available in a certain building with a composite shape, you would simply need to apply the same principles as you would use for calculating the area of a composite figure. The key to solving practical geometry problems is translation of the real-life situation into figures, measurements, and other information necessary to represent the situation conceptually. In this article, we will learn to apply geometric principles and techniques to solve problems. Geometry has a variety of real-life applications in everyday situations. O Apply geometry problem-solving techniques to practical situations O Identify some critical steps of the process for solving practical geometry problems
