Geogebra

is free software that can allow us to investigage both geometry and algebra . 

 It was invented by some teachers.   Here is a cool website to look at!  You can find the latest version of Geogebra on the school network drive -Look in Common$ W:\!Mathematics\Geogebra

We will use it to investigate:

Cube Volumes and face areas - Make your own investigation Cylinder Volumes ... Investigations in 3D -- download this zip file into your Maths Share Drive Geogebra Circle - Diameters Can we use a formula to work out the area of a circle sector? Use Geogebra to walk around the streets of the City of Melbourne. How do you know that a triangle is similar or congruent? What do you know about right angle triangles ? Using Geogebra to solve a parallel line problem from the Year 8 text book. Learn how to investigate the areas of polygons. Now try using Geogebra to investigate circumferences of circles What are the external angles of a triangle and a many-sided polygon? What do you know about the angles of the transversals of parallel lines? Use Geogebra to measure the angles in an Orienteering Course. or investigate the equations that draw graphs.
