Introduction
In geometry, a rotation is a transformation that turns a figure around a fixed point called the center of rotation. When a point is rotated 270° counterclockwise about the origin, its coordinates change. In this article, we will explore how to find the new coordinates of each point after a quadrilateral ABCD is rotated 270° counterclockwise about the origin.
Understanding Rotations
A rotation of 270° counterclockwise about the origin is equivalent to a rotation of 90° clockwise about the origin. This means that the new x-coordinate of a point will be the old y-coordinate, and the new y-coordinate will be the negative of the old x-coordinate.
Rotating Point A
Let's start by rotating point A, which has coordinates (6, 4). To rotate point A 270° counterclockwise about the origin, we need to swap its x and y coordinates and change the sign of the new x-coordinate.
x = 4
y = 6
new_x = -y
new_y = x
print(f"The new coordinates of point A are ({new_x}, {new_y})")
When we run this code, we get the following output:
The new coordinates of point A are (-6, 4)
Rotating Point B
Next, let's rotate point B, which has coordinates (4, 2). To rotate point B 270° counterclockwise about the origin, we need to swap its x and y coordinates and change the sign of the new x-coordinate.
x = 2
y = 4
new_x = -y
new_y = x
print(f"The new coordinates of point B are ({new_x}, {new_y})")
When we run this code, we get the following output:
The new coordinates of point B are (-4, 2)
Rotating Point C
Now, let's rotate point C, which has coordinates (2, 6). To rotate point C 270° counterclockwise about the origin, we need to swap its x and y coordinates and change the sign of the new x-coordinate.
x = 6
y = 2
new_x = -y
new_y = x
print(f"The new coordinates of point C are ({new_x}, {new_y})")
When we run this code, we get the following output:
The new coordinates of point C are (-2, 6)
Rotating Point D
Finally, let's rotate point D, which has coordinates (-6, -4). To rotate point D 270° counterclockwise about the origin, we need to swap its x and y coordinates and change the sign of the new x-coordinate.
x = -4
y = -6
new_x = -y
new_y = x
print(f"The new coordinates of point D are ({new_x}, {new_y})")
When we run this code, we get the following output:
The new coordinates of point D are (6, -4)
Conclusion
In this article, we explored how to find the new coordinates of each point after a quadrilateral ABCD is rotated 270° counterclockwise about the origin. We used Python code to demonstrate the rotation of each point and found the new coordinates of each point.
Step-by-Step Solution
Here is a step-by-step solution to the problem:
- Identify the coordinates of each point in the quadrilateral ABCD.
- To rotate a point 270° counterclockwise about the origin, swap its x and y coordinates and change the sign of the new x-coordinate.
- Use Python code to demonstrate the rotation of each point and find the new coordinates of each point.
Example Use Case
Suppose we have a quadrilateral ABCD with coordinates A(6, 4), B(4, 2), C(2, 6), and D(-6, -4). We want to rotate this quadrilateral 270° counterclockwise about the origin. Using the steps outlined above, we can find the new coordinates of each point as follows:
- Point A: (6, 4) → (-4, 6)
- Point B: (4, 2) → (-2, 4)
- Point C: (2, 6) → (-6, 2)
- Point D: (-6, -4) → (4, -6)
Code Solution
Here is a Python code solution to the problem:
def rotate_point(x, y):
new_x = -y
new_y = x
return new_x, new_y

A = (6, 4)
B = (4, 2)
C = (2, 6)
D = (-6, -4)
new_A = rotate_point(A[0], A[1])
new_B = rotate_point(B[0], B[1])
new_C = rotate_point(C[0], C[1])
new_D = rotate_point(D[0], D[1])
print(f"The new coordinates of point A are ({new_A[0]}, {new_A[1]})")
print(f"The new coordinates of point B are ({new_B[0]}, {new_B[1]})")
print(f"The new coordinates of point C are ({new_C[0]}, {new_C[1]})")
print(f"The new coordinates of point D are ({new_D[0]}, {new_D[1]})")
When we run this code, we get the following output:
The new coordinates of point A are (-4, 6)
The new coordinates of point B are (-2, 4)
The new coordinates of point C are (-6, 2)
The new coordinates of point D are (4, -6)
Final Answer
The new coordinates of each point after the quadrilateral ABCD is rotated 270° counterclockwise about the origin are:
- Point A: (-4, 6)
- Point B: (-2, 4)
- Point C: (-6, 2)
- Point D: (4, -6)
