Presentation transcript:

Label all points on the object

Always construct projection lines at 90 degrees to the axis of symmetry form points on the object

a1a1 Point “ a 1 ” is located on the projection line. “a1” is the same distance from the axial of symmetry as “ a ” but it is a mirrored image.

o1o1

You can see that the points are equal distance both sides of the axis of symmetry.

All points are always located as mirrored images on the projection lines

Join up the points to construct the mirrored image

The image is always mirrored and the same size as the object.
