Les treillis - À vous de jouer

S1 E7
·
2016

Lattices are the structures formed from different triangles. Our facilitator presents the equilateral and isosceles triangle and shares the particular properties of the triangle by explaining to us how to calculate the area. Subsequently, she tries to create different triangles from the same perimeter.
