Question
in this activity, you will reflect pre - images across the x - axis and y - axis and explore how the reflection affects the coordinates. place patty paper on the coordinate plane, trace figure j, and copy the labels for the vertices on the patty paper. a. reflect figure j across the x - axis. then, complete the table with the coordinates of the reflected figure.
| coordinates of j | coordinates of j |
|---|
|a(2, 5)|
|b(2, 1)|
|c(4, 1)|
|d(6, 3)|
|e(5, 4)|
|f(6, 6)|
compare the coordinates of figure j with the coordinates of figure j. how are the values of the coordinates the same? how are they different? explain your reasoning.
Step1: Aplicar regla de reflexión en el eje x
La regla para reflejar un punto $(x,y)$ en el eje x es $(x, - y)$.
Step2: Encontrar coordenadas de los puntos reflejados
Para $A(2,5)$, el punto reflejado $A'$ es $(2,-5)$.
Para $B(2,1)$, el punto reflejado $B'$ es $(2,-1)$.
Para $C(4,1)$, el punto reflejado $C'$ es $(4,-1)$.
Para $D(6,3)$, el punto reflejado $D'$ es $(6,-3)$.
Para $E(5,4)$, el punto reflejado $E'$ es $(5,-4)$.
Para $F(6,6)$, el punto reflejado $F'$ es $(6,-6)$.
