Introduction

In geometry, a dilation is a transformation that changes the size of a figure. It is a type of similarity transformation that preserves the shape of the figure but changes its size. In this article, we will analyze the coordinates of the vertices of triangle ABC and perform a dilation centered at the origin (0, 0) to produce a new triangle. We will use the coordinates of the vertices of triangle ABC to determine the coordinates of the vertices of the new triangle.

The Coordinates of the Vertices of Triangle ABC

The coordinates of the vertices of triangle ABC are given as A(9, -10), B(-15, 0), and C(15, 10). These coordinates represent the x and y coordinates of each vertex of the triangle.

Understanding Dilation

A dilation is a transformation that changes the size of a figure. It is a type of similarity transformation that preserves the shape of the figure but changes its size. In this case, we will perform a dilation centered at the origin (0, 0) to produce a new triangle.

Performing the Dilation

To perform the dilation, we need to multiply the coordinates of each vertex of triangle ABC by a scale factor. The scale factor is a number that determines the size of the new triangle. In this case, we will use a scale factor of 2.

Calculating the Coordinates of the Vertices of the New Triangle

To calculate the coordinates of the vertices of the new triangle, we need to multiply the coordinates of each vertex of triangle ABC by the scale factor of 2.

For vertex A(9, -10), the new coordinates will be A'(18, -20).
For vertex B(-15, 0), the new coordinates will be B'(-30, 0).
For vertex C(15, 10), the new coordinates will be C'(30, 20).

The Coordinates of the Vertices of the New Triangle

The coordinates of the vertices of the new triangle are A'(18, -20), B'(-30, 0), and C'(30, 20). These coordinates represent the x and y coordinates of each vertex of the new triangle.

Conclusion

In this article, we analyzed the coordinates of the vertices of triangle ABC and performed a dilation centered at the origin (0, 0) to produce a new triangle. We used the coordinates of the vertices of triangle ABC to determine the coordinates of the vertices of the new triangle. The coordinates of the vertices of the new triangle are A'(18, -20), B'(-30, 0), and C'(30, 20).
