Learn about the Four Transformations: Rotation, Reflection, Translation and Resizing
Start test. In this topic you will learn about the most useful math concept for creating video game graphics: geometric transformations, specifically translations, rotations, reflections, and dilations. You will learn how to perform the transformations, and how to map one figure into another using these transformations.
Rotation. Rotation is another common coordinate transformation. Consider the case of rotating the \(xy\)-plane about the origin by an angle \(\theta\), as in Figure \(\PageIndex{3}\). The origin of the resulting \(x'y'\)-plane is unchanged from the origin \(O=(0,0)\) of the \(xy\)-plane.
Moving around a fixed point is called rotation. Ahora ya sabes cómo mover objetos utilizando la traslación, la reflexión y la rotación. Comienza tu práctica a continuación.
Google Classroom. Learn what rotations are and how to perform them in our interactive widget. What is a rotation? In the figure below, one copy of the trapezoid is rotating around the point. In geometry, rotations make things turn in a cycle around a definite center point.
- I also made exactly this mistake. It says 255, not 225
- i agree with you bro
- when it puts - before the degrees it means counter clockwise and when there is no - it means clockwise
- STEP 1: Imagine that "orange" dot (that tool that you were playing with) is on top of point P. STEP 2: Point Q will be the point that will move clo...
- As long as you do not take a bite out of it, yes you can rotate a dorito.
- So the image of C is C′. you connect these points to point P to find the angle formed by these lines which is α+β. i hope this is clear enough for...
- those are lower case Greek letters which are often used to indicate measurement of angles. See https://www.ibiblio.org/koine/greek/lessons/alphabet...
Transformations in math involve changing a shape's position or which way the shape points. There are three main types: translations (moving the shape), rotations (turning the shape), and reflections (flipping the shape like a mirror image). Rigid transformations keep the shape's size and angles the same.

In geometry, a translation moves a thing up and down or left and right. Here, try translating this segment by dragging it from the middle, not the endpoints: Notice how the segment's direction and length stayed the same as you moved it. Translations only move things from one place to another; they don't change their size, arrangement, or direction.
