Translationof a 2-d shape causes sliding of that shape. To describe the position of the blue figure relative to the red figure, let’s observe the relative positions of their vertices. We need to find the positions of A′, B′, and C′ comparing its position with respect to the points A, B, and C. We find that A′, B′, and C′ are: 1. 8 units to the left...
We can apply the transformation rules to graphs of quadratic functions. This pre-image in the first function shows the function f(x) = x2. The transformation f(x) = (x+2)2shifts the parabola 2 steps right.
The type of transformation that occurs when each point in the shape is reflected over a line is called the reflection. 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. Every point (p,q) is reflected onto an image point (q,p). If point A is 3 units away fro...
The transformation that rotates each point in the shape at a certain number of degrees around that point is called rotation. The shape rotates counter-clockwise when the number of degrees is positive and rotates clockwise when the number of degrees is negative. The general rule of transformation of rotation about the origin is as follows. To rotate...
The transformation that causes the 2-d shape to stretch or shrink vertically or horizontally by a constant factor is called the dilation. The vertical stretch is given by the equation y = a.f(x). If a > 1, the function stretches with respect to the y-axis. If a < 1 the function shrinks with respect to the y-axis. The horizontal stretch is given by ...

Learn what transformations are and how they change the appearance of shapes without changing their size, shape or orientation. Explore the four types of transformations: rotation, translation, dilation and reflection, with examples and diagrams.
Learn what rigid transformations are and how they change the position and direction of a shape without changing its size or angles. Watch a video and see examples of translations, rotations and reflections, and ask questions in the comments.

- No.A transformation includes rotations, reflection, and translations. Translations just slide the figure around the grid.
- Nice question! A common type of non-rigid transformation is a dilation. A dilation is a similarity transformation that changes the size but not the...
- A side of a polygon is a type of line segment. Any line segment has infinitely many points, though its length is finite. Note that for any two dist...
- A *translation* (or "slide") is one type of transformation. In a translation, each point in a figure moves the same distance in the same direction....
- Dilations are not a rigid transformations. For something to be a rigid transformation, angles and side lengths need to stay the same. Dilations inc...
- There are 3 main types of rotations: 1.) 90∘ clockwise - To move a point or shape 90∘ clockwise, simply use this equation: (x, y) → (y, −x). 2.) 90...
- In most geometry courses this is taught early into the semester.
- I have that problem, too. But you only need to figure out how many degrees does the shape looking have. It needs more experience to do it.
- A dilation in math is an operation which make a shape that is smaller than the parent shape. Hope this helps!!
- It seems so. I believe any shape in the Euclidean space can make a rigid transformation.
