Choose the transformation matrices for rotation and reflection using the drop down list,
and explore the different effects using the handle at P to change the angles of rotation or the angle of the line of reflection with the x axis
Write down sample matrix calculations justifying and showing how points A and D are transformed by each of the rotations about O or reflections in the line through O.
Suggested calculations :
(1) Rotation of Point A 90 deg anticlockwise
(2) Rotation of Point D 90 deg anticlockwise
(3) Rotation of Point A 180 deg clockwise
(4) Rotation of Point D 180 deg clockwise
(5) Reflection of Point A in line making angle of 90 deg anticlockwise with x axis
(6) Reflection of Point D in line making angle of 90 deg anticlockwise with x axis
(7) Reflection of Point A in line making angle of 180 deg anticlockwise with x axis
(8) Reflection of Point D in line making angle of 180 deg anticlockwise with x axis
