PPT-Transformations and Symmetry

Vocabulary Image The result of moving all points of a figure according to a transformation Transformation The rule that assigns to each point of a figure another point in the plane Vocabulary. 1 2D Transformations Given a point cloud polygon or sampled parametric curve w e can use transformations for several purposes 1 Change coordinate frames world window viewport devic e etc 2 Compose objects of simple parts with local scaleposition orie a 12 22 a a mn is an arbitrary matrix Rescaling The simplest types of linear transformations are rescaling maps Consider the map on corresponding to the matrix 2 0 0 3 That is 7 2 0 0 3 00 brPage 2br Shears The next simplest type of linear transfo Terra Alta/East Preston School. Rotational Symmetry. If, when you rotate a shape, it looks exactly the same as it did in its original position, then we say that the shape has . rotational symmetry. .. Ch. 2 Lesson 3. Pg. 123. What will you will learn?. Enlarge Photographs. Make something from a pattern. Identify Similarity. Two figures are . similar. if the second can be obtained from the first by a sequence of transformations and dilations. Ahhhh. Isn't symmetry wonderful?. Symmetry is all around us. It's in our art, nature and even ourselves. It has been proven that we find things with symmetry more pretty. So in order to have prettier math, we should learn about it, don't you think.. Lecture 3. Jitendra. Malik. Pose and Shape. Rotations and reflections are examples. of orthogonal transformations . Rigid body motions. (Euclidean transformations / . isometries. ). Theorem:. Any rigid body motion can be expressed as an orthogonal transformation followed by a translation.. Is it possible to trace the following figure without retracing any lines and without lifting your pencil from the paper? If yes, trace the route. If not, explain why it is not possible. Solve for x .

Students should have paper and a pencil for notes at their desk while going through this presentation.. Transformation: a transformation is a change in position, shape or size.. in real life. HW: Maintenance Sheet 3 . (7-8). I can use the properties of translations, rotations, and reflections on line segments, angles, parallel lines or geometric figures. . I can show and explain two figures are congruent using transformations (explaining the series of transformations used) . Identify line and rotational symmetries in two-dimensional figures.. Identify line and rotational symmetries in three-dimensional figures.. Definitions. A figure has . symmetry. is there exists a rigid motion (reflection, translation, rotation, or glide reflection that maps the figures unto itself..
