After completing this tutorial, you will be able to complete the following:
Which four types of transformations are discussed in the Animation?
~ The transformations discussed in the Animation are reflections, rotations, translations, and glide reflections.
For questions 2-5, consider the following diagram:
Which transformation transforms the white shape into the blue shape? Explain how you know this.
~ The blue shape and the white shape are symmetrical. Therefore, a reflection in a line transforms the white shape into the blue shape.
Which transformation transforms the white shape into the purple shape? Explain how you know this.
~ The white and purple shapes have the same direction, and they are not symmetrical. Only the position of the shapes is different. Therefore, a translation transforms the white shape into the purple shape.
Which transformation transforms the white shape into the pink shape? Explain how you know this.
~ We can see that both the direction and the position of the shape have changed when comparing the pink shape to the white shape. Therefore, a rotation transforms the white shape into the pink shape.
Which transformation transforms the white shape into the yellow shape? Explain how you know this.
~ The yellow shape and white shape are symmetrical, but the yellow shape is a translation of a reflection of the white shape. Therefore, a glide reflection transforms the white shape into the yellow shape.
