Geometry is the visual study of shapes, sizes, patterns, and positions. It occurred in all
cultures, through at least one of these five strands of human activities:
1. building/structures (building/repairing a house, laying out a garden, making a
2. machines/motion (using a pry-bar, riding a bike, sawing a board, swinging, …)
3. navigating/star-gazing (How do I get from here to there?, using maps, …)
4. art/patterns (designs, symmetries, representations, …).
5. measurement (How big is it?, How far is it?, ...)
In order to solve a geometry word problem, you need to read the problem carefully, recognize shapes in the drawing, pay attention to labels, and use whatever formulas you have to help you answer the question.
There are many geometric formulas, and they relate height, width, length, or radius, etc, to perimeter, area, surface area, or volume, etc. Some of the formulas are rather complicated, and you hardly ever see them, let alone use them.
