Grade 5 · Unit 8: Location and transformation

Transformations

Translate, reflect, rotate.

Jamdani sarees use repeated and reflected motifs.

Patterns in textiles

Jamdani weavers repeat motifs across the cloth. They slide, flip and turn the designs. These are transformations: translation, reflection and rotation.

Translation

Every point moves the same way. Describe it: 5 right, 3 up. The image is congruent to the object.

Reflection

A reflection flips the shape over a mirror line. Points are the same distance from the line on both sides. The shape faces the other way.

Rotation

A rotation turns a shape about a point. Say the angle (90°, 180°), the direction, and the centre. Tracing paper helps you rotate accurately.
