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

A vector can be used to describe a translation.

Describing a translation

Maths

In this unit, pupils explore the effects of different transformations and whether the transformed shape is congruent or similar to the original shape. This is built on in the future unit where pupils formalise the criteria for determining congruence in triangles and study rotational symmetry

In this unit, pupils translated and reflected simple shapes on the full coordinate grid. In this unit, these processes are formalised and rotation and enlargement are introduced

Transformations

Displacement is the {{ }} from the starting point when measured in a straight line. 

$${2\choose 1}$$ is a column vector. It has two numbers. Match each number with its meaning.

Which of the following shows a translation by $${2 \choose -3}$$?

A triangle ABC is translated. The corresponding coordinates are A(1,5) and $$A^{\prime}$$(2,7), B(5,8) and $$B^{\prime}$$(6, 10).  C has coordinates (4,7). Work out the coordinates of the image of C.

{{ }} is a transformation in which every point of a shape moves the same distance in the same direction.

Which of these images do not show a translation?

Which one of the following shapes cannot be translated onto one of the other shapes? [IMG 7.10.3.s3]

When a translation takes place, the invariant properties of a shape are

Which of these contains a non-translated shape?
