Invariant properties resources

Students enlarge a diagram to a given scale.

This task requires students to indicate, in a table, the invariant properties of four transformations (translation, reflection, rotation, enlargement) of a picture of a traffic light.

In this practical task students use a ruler, a protractor, and a compass to enlarge an arrow by two given scale factors. They then complete a table to show the invariant properties.

Students identify the invariant properties of a translated and an enlarged shape.

Students identify invariant properties for enlargement.

This task requires students to indicate the invariant properties of four transformations (translation, reflection, rotation, enlargement).

Students work out area, length and angles of a shape after enlargement.
