Inhoud

Aktiwiteit: getallepatrone (driehoekgetalle) [lo 2.3]

7. Kom ons ondersoek ook DRIEHOEKGETALLE.

  • Kyk goed na die volgende:

a) Voltooi nou die tabel:

Skets 1 2 3 4
Aantal driehoeke

b) Teken nou skets 5 en 6 en vul die tabel verder in.

C. let op?

Ons kan die volgende formule gebruik om die aantal driehoeke in elke skets te bepaal:

Bv. Skets 5 (S 5 ) = 5 × (5 + 1) ÷ 2 = 15

(i) Gebruik die formule en bepaal: (gebruik jou sakrekenaar, indien nodig)
