What did the little acorn say when he grew up? Geometry (Gee, I’m a tree)!
Sorry for the ‘teacher’ joke.
As soon as we begin to enquire about shapes, we are ‘speaking’ geometry. Originally, it was the mathematics of measuring the Earth, surveying blocks of land for farming, for example. In Egypt, geometry was used to replace boundary markers between properties after the Nile flooded each year. The term geometry comes from the Greek words γη (ge-) or γαια (Gaia) meaning earth, ground or land, and μέτρον (métron) meaning measure.
Geometry can be regarded as the discipline of studying abstract shapes with their properties and relationships. It can also be thought of in very practical terms. Tradespeople use geometry every day of their lives, making sure walls or frames are square, having the correct gradients for trusses, roofs, pathways, stormwater, etc. I have workmen on my roof at the moment, replacing corrugated iron sheeting. The art of cutting the sheeting to fit involves some clever geometry!
All the different facets of geometry result from our asking curious questions. At least, someone asked these questions:
Graeme Henderson tutored me throughout my entire high school mathematics education, and through his expert tutelage and exceptional ability to explain the concepts that would otherwise be very hard to understand, I was able to grasp and excel at topics that I would have otherwise been unable to. He was an excellent tutor, and I would not hesitate to recommend him to anyone looking for help with mathematics problems!
