=== Spelar det någon roll var höjden står? ===
En triangel med en bestämd längd på basen och höjden. Har den olika area om höjden ritas på olika ställen? Eller spelar det ingen roll?

Lektion 9 - Area

Mål. Förstå (och räkna med) begreppen area och omkrets för en rektangel, triangel. Kunna rita figurer utifrån en given omkrets. Ex rita en rektangel med omkretsen 14cm.

Film. Gösses Area för triangeln.


Årstaskolan Stockholm - Kunskapshubben

Bra att känna till. Parallellogrammen har arean = basen * höjden. Höjden är den streckade linjen i figuren. Basen är längden på den undre sidan.

Spelar det någon roll var höjden står?

En triangel med en bestämd längd på basen och höjden. Har den olika area om höjden ritas på olika ställen? Eller spelar det ingen roll?

Dra i glidaren och testa!
