Throughout this section, you will use your visualization to move between a 2D and 3D space through the use of orthographic drawings. Orthographic drawings are representations of 3D objects on a 2D plane from various viewing points. When visualizing the possible solutions take care and look at all of the views before selecting what you think is the correct answer.
Watch the tutorial picture to find out the principles of orthographic projection. Then using the coloured cubes and the worksheets for orthographic drawings complete the activities. Once you feel confident about the completed activities you can begin the quiz.
