En aquest article us parlarem sobre el que hem fet de geometria aquest primer trimestre.<\/span><\/p>\n

El curs passat, vam estar treballant la mesura (sistema m\u00e8tric decimal) i vam comen\u00e7ar aquest bloc de continguts.\u00a0<\/span><\/p>\n

La primera activitat que hem fet aquest curs ha sigut fer un rep\u00e0s de qu\u00e8 ja hav\u00edem treballat l\u2019any passat de geometria. Vam repassar els angles (recte, pla, complet i agut, obt\u00fas); els pol\u00edgons (regulars, irregulars i els \u201cno pol\u00edgons\u201d); el punt, la l\u00ednia i el segment; el que \u00e9s una figura geom\u00e8trica i un cos geom\u00e8tric i per \u00faltim, vam repassar el per\u00edmetre i l\u2019\u00e0rea.<\/span><\/p>\n

El seg\u00fcent que hem fet despr\u00e9s del rep\u00e0s ha sigut calcular \u00e0rees de diferents figures geom\u00e8triques. Hem calculat les \u00e0rees del quadrat, el rectangle, el triangle, el rombe, el romboide, el trapezi, el trapezoide i l\u2019hex\u00e0gon. Hem comen\u00e7at calculant les del quadrat i el rectangle, que el nostre mestre, que es diu Ciscu, ens va dir que per a calcular aquestes dues \u00e0rees hav\u00edem de fer <\/span>base x altura <\/b>(B x H) i per la del quadrat <\/span>costat<\/b>2<\/b><\/sup> (C<\/span>2<\/span><\/sup>).\u00a0<\/span><\/p>\n

Llavors hem fet l\u2019\u00e0rea del triangle. El mestre ens va dir que per aconseguir saber les \u00e0rees de totes les figures geom\u00e8triques hav\u00edem d\u2019aconseguir formar o un quadrat o un rectangle. Ens va repartir dos papers amb forma de triangle i ajuntant-los o retallant-los vam haver d\u2019aconseguir formar un quadrat o un rectangle, perqu\u00e8 despr\u00e9s d\u2019aix\u00f2 ens seria molt m\u00e9s f\u00e0cil trobar quan feia l\u2019\u00e0rea del triangle. I despr\u00e9s vam intentar buscar la f\u00f3rmula. Alguns la van trobar i d\u2019altres no. La f\u00f3rmula \u00e9s: B\u00b7H\/2.<\/span><\/p>\n

El mateix vam repetir amb totes les altres figures geom\u00e8triques i al final vam descobrir les f\u00f3rmules de les figures, que s\u00f3n:<\/span><\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

Finalment, el que hem fet ha sigut calcular l\u2019\u00e0rea i el per\u00edmetre de dues figures estranyes. Aquestes, separant-les per trapezis, rectangles, quadrats\u2026 hem aconseguit esbrinar l\u2019\u00e0rea i el per\u00edmetre.<\/span><\/p>\n

El segon trimestre farem volums i cossos geom\u00e8trics.<\/span><\/p>\n
