Amb aquestes tres peces, forma una figura amb un eix de simetria.

«Traple» és #unaideammaca del Sándor Bozóki que permet parlar de quadrilàters, raons de semblança, simetries, rep-tiles i enrajolats del pla.

Us animeu a dur-lo a l'aula?

Quines altres propietats pots veure quan afegim graelles 8×8 o 6×6?

Sabies que pots formar un triangle 3:4:5 fent dos plecs en un quadrat de paper?

Només cal fer servir el primer plec per trobar el punt mitjà del costat esquerre i l'altre per dur la cantonada inferior dreta fins allà!

A generalization of the ideas that x.com/tiago_hands & x.com/mathsproofs have been developing lately:

Because of the Law of Sines, if you draw rhombi with side lengths = √circumdiameter in the corners of any triangle, then their areas are equal to the lengths of the opposite sides: A=a, B=b & C=c.

What are the areas of these quadrilaterals?
What are their angles?

x.com/tiago_hands and x.com/mathsproofs are working really hard in these objects, follow them to get updates!!!
