Key learning points

1. It can be helpful to choose a vertex and translate that.
2. Once all the vertices have been translated, the image can be drawn.
3. The image and the object should be congruent.
4. To translate, you need to know the distance left/right and up/down to move.

Keywords

• 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.

• Vector - A vector can be used to describe a translation.

• Vertex - A vertex is the point where two or more line segments meet. The plural is vertices.

• Displacement - Displacement is the distance from the starting point when measured in a straight line.
