If you are a geometry teacher and have not heard the question, When will we ever use this stuff in real life? you haven’t gotten past the first day of class. If you haven’t heard it at least a thousand times, you are nowhere close to retirement.
Farmers, landscapers, surveyors, contractors, those who lay carpet and a whole host of others need to be experts in figuring area and perimeter. Every profession requires its members to know a bit about logic; however, teachers, administrators, doctors, lawyers and politicians need to be particularly adept in that area. Artists and architects need to understand how similar figures are calculated and be very knowledgeable about the characteristics of three-dimensional figures.
About this time, the student who asked the question blurts out, All that’s fine, but suppose I’m not going to do any of those jobs? Instead of asking the student if there is a particular job he would like you to discuss, why not refer to this list to explain why geometry is important in everyone’s life. Afterwards, he is bound to come to the realization he uses geometric concepts every single day without ever thinking about it.
