Series 2: Describe the geometric transformations
This provides pairs of short movies showing a rotation followed by a second rotation applied to a collection of dots. In each pair, one of the movies shows a TRACE of the dots' movements (as below). Students are asked to describe the resultant transformation.
Describe the geometric transformations (A)

This involves two 90˚ rotations.

Describe the geometric transformations (B)

This involves another two 90˚ rotations.

Describe the geometric transformations (C)

This involves rotations of 60˚ and 120˚.

Describe the geometric transformations (D)

This involves the previous rotations of 60˚ and 120˚ but in reverse order.
