EASIER THAN YOU THINK...

Geometry

Two hands constructing a regular hexagon with pair of compasses and straight edgeWhat 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:

I attend university in the US and am starting the more difficult math courses. I have never studied and managed to stumble along for a very long time and now I have no idea what I am doing. I can follow along with lecture and understand what they are saying but when left on my own I have no clue what to do and where to start. So I’ve recommitted to start over and build a solid foundation. Looking around youtube alot I have found some good quick fix stuff but man I am converted to Graeme Hendersen. I really appreciate your very thorough approach to learning and can’t get enough of your explaining mathematical concepts. I am eating up everything and am excited to master math. Man, I sound super nerdy but it’s true. Thanks
