2D Cavalieri Principle Demo

This GeoGebra applet presents area of a triangle as 2D Cavalieri Principle demo. Cavalieri Principle in 2D states that if two regions in a plane are included between parallel lines in the plane and if every line parallel to these two lines intersects in segments of equal length then the two regions have equal area. In the applet area has been calculated dynamically using Heron's formula. For more on Cavalieri's principle and its use check my online book "Flipped Classroom Calculus of Single Variable" https://versal.com/learn/vh45au/
