  1. Ⅰ 도 형 4. 도형의 이동 2) 대칭이동 (Symmetric transformation)

  2. ▷ 점의 평행이동 ☞ g : (x, y) → (x + a, y + b) ▷ 도형의 평행이동 ☞ f( x, y ) = 0 → f(x – a, y – b) = 0

  3. 점의 대칭이동 X 축 , f : (x , y) → (x, -y) y 축 , f : (x , y) → (-x, y) 원점 , f : (x , y) → (-x, -y)

  4. 점 (4, 5)를 x축, y축, 원점에 대하여 대칭시켜 보라구~~~

  5. 도형의 대칭이동??? 함 볼까?

  6. 도형의 대칭이동 X 축 , f (x , y) = 0 → f (x, -y) = 0 y 축 , f (x , y) = 0 → f (-x, y) = 0 원점 , f (x , y) = 0 → f (-x, -y) = 0

  7. [문제] 원 을 원점에 대하여 대칭이동 하면 직선 3x + 2y + k = 0 에 의하여 넓이가 이등분 될 때, 상수 k값을 구하면?
