A Power Point presentation investigating the not-so-obvious question of where the centre of a triangle is. Useful to revise and motivate some of the line work in e.g. Higher Maths
Starts with the centre of other shapes (e.g. circle - easy) before introducing the main candidates for the centre of a triangle. These are where the medians, perpendicular bisectors, and altitudes meet. But there are also many other centres. And what about quadrilaterals, or 3D shapes?

Thank you for sharing your work. It does a good job of extending students past the curriculum!
A really interesting lesson that could be used to extend a constructions unit. Possibility for several lessons of investigative work here. Thank you for sharing!
