What is geometry is it a translation?
In geometry, a translation is a rigid transformation that does not change the size or shape of the original figure. It is one of the most common types of transformations used to change a figure or shape into another.

A translation transforms a figure in the coordinate plane by moving all points of the figure in the same direction in the same number of units and by changing their x-coordinate to (x + k, y + k). For example, translate the triangle A(-6,2),B(-4,3),C(-2,1) by 4 points to the right and up 3 units and the parallelogram PQ by -8 units horizontally and +4 vertically.
What are the rules of translations?
A translation moves a shape to the left by k units and replaces x with x – k. A negative translation moves the shape to the right by k units and replaces y with x – k.
What is the difference between a translation and a rotation?
A rotation is a different type of displacement where the object is displaced in a different direction. A rotation changes an object’s position in space, while a translation does not change the position of an object in space.
What is a pre-image and an image?
A pre-image is the initial position of the shape or figure. An image is the new position of the shape after the translation process. The new position of the image is always a faithful reproduction of the pre-image, but in a different place on the coordinate grid.
What is the rule for horizontal and vertical translations?
A horizontal translation is a slide from left to right or vice versa along the x-axis, while a vertical translation is a slide up or down along the y-axis.
What is the rule for translating functions?
If you graph the function f(x) in math, you will find that it is translated horizontally by 2 points. For this reason, g(x)=f(x-k)+C is the same graph as f(x), but it has a translation of 2 and the h(x)=f(x-k)2 formula is the same graph as f(x) with a horizontal translation of 2.
What is the rule for combining coordinates with a translation?
To combine coordinates with a translation, you need to set the old x-coordinates of each point to x – k and then solve for x. Then you will get a new x-coordinate for each point, which is the same as x – k.
When you want to translate a function f, you have to find the new coordinates of each point of the graph. You can use a calculator to do this, or you can use the sketch method.
What is the rule for translating a function with a plus sign?
If you put a plus sign in the function f, it is a horizontal translation. If you put a minus sign in the function f, it is vertical. For this reason, g(x)=f(x-k)+C must be the same graph as f, but it has a translation of 1 and the h(x)=f(x-k)2 is the same graph as f with a vertical translation of 1.
A transformation can be horizontal or vertical or both. In general, translations can be represented by a column vector where a is the number of units moved to the right or left and b is the number of units moved up or down.
