Topic: GeoGebra
Sub-topics:
Circle theorems
Investigate using GeoGebra these circle theorems: angles at the centre and at the circumference, angle in a semicircle, angles in the same segment, angles in a cyclic quadlateral, length of tangents, angle between circle tangent and radius, alternate segment theorem.
Construct with GeoGebra
“The 7 Basic C&S Constructions with GeoGebra”. Each page includes a video (YouTube and TeacherTube for where YouTube is blocked), a working sample of the construction to be created and a blank GeoGebra page to complete the construction.
Using technology to create constructions normally done by hand helps you to see why we use a compass to complete the constructions.
Exploring Absolute Value Equations
Explore the solution of equations in the form | ax + b | = cx + d.
