Transformation Geometry is the study of moving an image into different positions and orientations.
It has 5 main topics: - Axial Symmetry - Central Symmetry - Translation - Enlargements and Reductions - Rotations These topics very useful and applicable other topics of graphical education especially axial symmetry. It can be used to speed up the process of drawings in many topics such as the parabola. Translation is often used as part of the ellipse question in exams also. Transformation Geometry comes up as question 5 in the Junior Certificate exam. Exam Tips: - Ensure that lines that are for translation are parallel. Having one line slightly non-parallel will distort the image. - Ensure that lines for central symmetry and rotations are accurately meeting the point they are supposed to. Again any slight inaccuracies will lead to distortion of the image. - Plan carefully where to start the question. Translations such as rotations can often lead to the drawing moving off the page if it is not positioned correctly. - Keep your drawing neat and tidy. Light construction lines and only heavy in whats needed. Only heavy in the image when you know it's correct. |
