A vector can be used to describe a translation.

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

If one shape can fit exactly on top of another using rotation, reflection or translation, then the shapes are congruent.

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

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

Q1) On this keyboard, which letter do you type next if you start on 'r' and move 5 to the right and up 1?

{{ }} can be used to help replicate translating the whole object in one movement.

The coordinate (3, 7) is translated right by 4 and up by 1. What is the coordinate of the image?

A translation by $${4 \choose -3}$$ is being applied to object ABCDE. Which vertex has been translated?

This shape is translated. $$D^{\prime}$$ is at $$(120, -12)$$ what are the coordinates of $$C^{\prime}$$?

An object is translated 4 right and 3 down. What number would be in the second position of the vector for this translation $$1^{st} \choose 2^{nd}$$?

The vector $${-3 \choose 7}$$ shows the translation {{ }} by 3 units and up by 7 units.

$${4 \choose 3}$$ is an example of {{ }} notation.  This type of notation can be used to describe a translation.

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

Has a translation taken place? $$A(3,4) \mapsto A^{\prime}(5,7) $$, $$B(5,8) \mapsto B^{\prime}(7,11) $$ and $$C(0,5) \mapsto C^{\prime}(2,7) $$?

This lesson will soon be taken down.
