- Mary Abiva
In this unit, we talk about 3 types of rigid transformations:
Translations / Traslación
Reflections / Reflexión
Rotations / Rotación
Last class, we talked about Translations.
This class, we are going to talk about Reflections!
Reflection: A transformation across a line. This will create a mirror image on the other side of the line.
Reflexión: Una transformación a través de una línea. Esto creará una imagen reflejada en el otro lado de la línea.
In the activity below, use the checkboxes to reflect the Preimage across the y-axis and the x-axis!
Move around the points of the Preimage to see how that will change the reflections!
What do you notice about the points from the Preimage and the Image from reflecting across the y-axis?
What do you notice about the points from the Preimage and the Image from reflecting across the x-axis?
