Question
A polygon after translation is called
- Sliding
- Change
- Pre-image
- Image
Hint:
The translation is the act of moving a shape or a figure from one location to another. A figure can move in translation up, down, right, left, or anywhere else in the coordinate system. Only the object's position changes during translation; its size stays the same.
We have asked what is polygon called after translation.
The correct answer is: Image
Now as we said that in translation, a point or a figure can move up, down, right, left, or anywhere else in the coordinate system. Any point can be located using a Cartesian coordinate system or coordinate system, and that point can be displayed as an ordered pair (x, y) known as Coordinates.
In cartesian plane there are 4 quadrants:
1st Quadrant
2nd Quadrant
3rd Quadrant
4th Quadrant
The sign patterns are in this way:
I- quadrant (+, +)
II-quadrant (-, +)
III-quadrant (-, -)
IV-quadrant (+, -)
Lets take an example:
(x, y) --> (x - 9, y + 3)
(x, y) --> (x + 2, y + 5)
So with these examples, we can see that a new image is formed. So a polygon is called as image after translation.
In this question, we used the concept of translation and found out the points according to the condition given. We also understood the concept of the cartesian system and the coordinates. In translation, only the position of the object changes, its size remains the same. A polygon after translation is called Image.
