![]() The shape rotates counter-clockwise when the number of degrees is positive and rotates clockwise when the number of degrees is negative. The transformation that rotates each point in the shape at a certain number of degrees around that point is called rotation. The transformation of f(x) is g(x) = - x 3 that is the reflection of the f(x) about the x-axis. Here is the graph of a quadratic function that shows the transformation of reflection. Thus the line of reflection acts as a perpendicular bisector between the corresponding points of the image and the pre-image. If point A is 3 units away from the line of reflection to the right of the line, then point A' will be 3 units away from the line of reflection to the left of the line. Every point (p,q) is reflected onto an image point (q,p). When the points are reflected over a line, the image is at the same distance from the line as the pre-image but on the other side of the line. The type of transformation that occurs when each point in the shape is reflected over a line is called the reflection. The transformation f(x) = (x+2) 2 shifts the parabola 2 steps right. This pre-image in the first function shows the function f(x) = x 2. We can apply the transformation rules to graphs of quadratic functions. This translation can algebraically be translated as 8 units left and 3 units down. 3 units below A, B, and C respectively.8 units to the left of A, B, and C respectively. ![]() We need to find the positions of A′, B′, and C′ comparing its position with respect to the points A, B, and C. To describe the position of the blue figure relative to the red figure, let’s observe the relative positions of their vertices. Translation of a 2-d shape causes sliding of that shape. Transformations help us visualize and learn the equations in algebra. We can use the formula of transformations in graphical functions to obtain the graph just by transforming the basic or the parent function, and thereby move the graph around, rather than tabulating the coordinate values. Transformations are commonly found in algebraic functions. Transformations can be represented algebraically and graphically. Here are the rules for transformations of function that could be applied to the graphs of functions. On a coordinate grid, we use the x-axis and y-axis to measure the movement. Symmetry is a fundamental aspect of geometry both in the environment and in design.Consider a function f(x). Knowledge of how certain shapes will tessellate allows tilers, paving companies and architects to design spaces efficiently and creatively. This is an important range of spatial reasoning skills that are used to solve problems in a range of real-life situations and occupations. The essence of Teaching Transformations is to enable students to develop their ability to identify the properties of shapes and objects and how they can be combined.

Teaching Flip, Slides, Turns, Dilations & Symmetry is taught from Year 2 onwards. Teaching Transforming 2D Shapes is a Measurement & Geometry topic, and it’s part of the Location & Transformation sub-strand area. ![]() I like to start a unit on transformations by encouraging students to find examples of flip, slide & turns around the classroom, school & environment. ![]() They use transformation understanding to create and design patterns which can be used in so many different areas, including: So many professions use transformation skills, including Architects, Artists, and Designers.
