GeoGebra Tool for Signed Areas | Algebraic Calculus One | Anna Tomskova
Dr Anna Tomskova explains how to create a tool with GeoGebra to calculate the signed area of a triangle, and uses it to verify an additive identity for signed areas of triangles. This is part of the Algebraic Calculus One course.

My research papers can be found at my Research Gate page, at https://www.researchgate.net/profile/Norman_Wildberger
My blog is at http://njwildberger.com/, where I will discuss lots of foundational issues, along with other things.
Online courses will be developed at openlearning.com. The first one, already underway is Algebraic Calculus One at https://www.openlearning.com/courses/algebraic-calculus-one/ Please join us for an exciting new approach to one of mathematics' most important subjects!
