  • Triângulo rectângulo: b = base, h = altura, logo área = ( b × h )/2 e perímetro = b + h + (b2+h2)1/2.

    Arraste o ponto A para ver a variação do perímetro e da área com a variação da base e da altura:

  • Quadrado: a = lado (ou aresta), logo área = a2 e perímetro = 4a.

    Arraste o ponto A para ver a variação do perímetro e da área com a variação da aresta:

  • Rectangulo: a = lado 1, b = lado 2, logo área = a×b e perímetro = 2a + 2b.

    Arraste o ponto A para ver a variação do perímetro e da área com a variação dos lados:

  • Círculo: r = raio do círculo, logo área = πr2 e perímetro = 2πr.

    Arraste o ponto P para ver a variação do perímetro da circunferência e da área do círculo com a variação do raio:
