My name is Panagiota Argyri, I am mathematician to Model High School Evangeliki of Smyrni <br />(Athens , Greece). I am Scientix ambassador from 2014. I am exciting with this discussion forum. I love challenges based on science literature. <br />Chapter 3 : Dedicated to Thales.<br />Playing with shadows for calculate the height of pyramid of Cheops.<br /><u>Mathematical and Geometrical concepts based on Chapter 3 for teaching Geometry : <br /></u>Theorem of Thale for parallels lines, similarity of triangles and polygons, equal rates <br />for analogy ammounts. <br />An iquiry lesson plan based on chapter 3 :<br /><a href="https://www.slideshare.net/PanagiotaArgiri/thales-75406760">https://www.slideshare.net/PanagiotaArgiri/thales-75406760<br /><br /></a>Using mathematical software Geogebra for activities and exercises based on Chapter 3 Parrot&#39;s Theorem <br /><br /><a href="https://ggbm.at/EhPe2t6N">https://ggbm.at/EhPe2t6N<br /><br /></a><a href="https://ggbm.at/n2QWdStV">https://ggbm.at/n2QWdStV<br /></a><br /><a href="https://ggbm.at/y4SerXBN">https://ggbm.at/y4SerXBN</a><br /><br /><a href="https://ggbm.at/zhtXCzjr">https://ggbm.at/zhtXCzjr</a><br /><br />Video reviewing chapter 3 :<br /><a href="https://youtu.be/0P1Nc1t8vWg">https://youtu.be/0P1Nc1t8vWg</a><br /><br />(Note : Not only Thales..but also..Eratoshenes playied with shadows for calculate the cirtumance of Earth)
