A quadrilateral is a four-sided polygon that consists of four straight line segments. It is a two dimensional shape that can be transformed into different shapes by rotating, reflecting, or translating it. Transformation is the process of changing the form or position of an object. In this article, we will discuss the transformation of a quadrilateral ABCD after a rotation of 90 degrees.

## Before the Transformation

A quadrilateral ABCD is a four-sided polygon with four vertices A, B, C, and D. The sides of a quadrilateral can be either parallel or non-parallel. The image of a quadrilateral ABCD can be represented by the following figure:

## After the Transformation

When the quadrilateral ABCD is subjected to a rotation of 90 degrees, the image of the quadrilateral ABCD is transformed into a different shape. The image of the quadrilateral ABCD after the transformation is given in the following figure:

The image of the quadrilateral ABCD after the transformation shows that the four vertices A, B, C, and D have moved in a clockwise direction by 90 degrees. The sides of the quadrilateral ABCD have also changed in length and direction.

In conclusion, the image of a quadrilateral ABCD after a rotation of 90 degrees is different from the original image of the quadrilateral ABCD. The transformation of the quadrilateral ABCD has resulted in the vertices of the quadrilateral ABCD moving in a clockwise direction and the sides of the quadrilateral ABCD changing in length and direction.

The properties of a quadrilateral ABCD can be modified through a linear transformation known as the R0, 90° transformation. This transformation involves four distinct operations: rotation, reflection, scaling, and translation. Through these operations, the image of the quadrilateral ABCD can be completely transformed.

In the R0, 90° transformation, the rotational operation is the most significant factor in determining the image of the quadrilateral. This technique rotates the object around the origin, 90° counter clockwise, resulting in an image that is rotated 90° from the original.

In addition to rotation, the reflection of the object is also an important factor in creating the image. Reflection involves flipping the object across a specified line of symmetry. In the case of the R0, 90° transformation, the line of symmetry runs vertically along the origin. The reflection therefore creates a point of symmetry along the origin which alters the shape of the original quadrilateral.

Scaling, another operation in the R0, 90° transformation, acts to increase or decrease the size of the object. This is typically done by multiplying the coordinates of all the vertices of the quadrilateral by a fixed number, allowing the size of the image to be altered.

Finally, translation is a crucial element of the R0, 90° transformation. This technique shifts the coordinates of an object from one point to another. This allows the image of the quadrilateral to move relative to the origin, creating a variety of different images.

The combination of these operations results in the R0, 90° transformation, which effectively produces a new image of the quadrilateral ABCD. This image is characterized by a 90° rotation, the creation of a point of symmetry, changes in size, and shifts in coordinates.
