Lesson Details
Key learning points
- It can be helpful to choose a vertex and translate that.
- Once all the vertices have been translated, the image can be drawn.
- The image and the object should be congruent.
Common misconception
Students may translate vertically before horizontally.
Remind the students that the column vectors work in the same way as coordinates.
Keywords
Vector - A vector can be used to describe a translation.
Translation - Translation is a transformation in which every point of a shape moves the same distance in the same direction.
Congruent - If one shape can fit exactly on top of another using rotation, reflection or translation, then the shapes are congruent.
Vertex - A vertex is the point where two or more line segments meet. The plural is vertices.
