Understanding Reflections Across Both Axes

In mathematics, reflections across both axes refer to the process of flipping a point or a shape across both the x-axis and the y-axis. This concept is crucial in geometry and is used to solve various problems related to coordinate geometry. In this article, we will explore the concept of reflections across both axes and identify the points that are reflections of each other across both axes.

What are Reflections Across Both Axes?

Reflections across both axes involve flipping a point or a shape across both the x-axis and the y-axis. When a point is reflected across the x-axis, its y-coordinate changes sign, and when it is reflected across the y-axis, its x-coordinate changes sign. Therefore, when a point is reflected across both axes, both its x and y coordinates change sign.

How to Identify Reflections Across Both Axes

To identify reflections across both axes, we need to find the points that are symmetric with respect to both the x-axis and the y-axis. This can be done by changing the sign of both the x and y coordinates of the given point.

Example 1: Reflection of (-2, 8) Across Both Axes

Let's consider the point (-2, 8). To find its reflection across both axes, we need to change the sign of both the x and y coordinates. Therefore, the reflection of (-2, 8) across both axes is (2, -8).

Example 2: Reflection of (5, -6) Across Both Axes

Now, let's consider the point (5, -6). To find its reflection across both axes, we need to change the sign of both the x and y coordinates. Therefore, the reflection of (5, -6) across both axes is (-5, 6).

Example 3: Reflection of (4, -3) Across Both Axes

Finally, let's consider the point (4, -3). To find its reflection across both axes, we need to change the sign of both the x and y coordinates. Therefore, the reflection of (4, -3) across both axes is (-4, 3).

Which Points are Reflections of Each Other Across Both Axes?

Now that we have understood the concept of reflections across both axes, let's identify the points that are reflections of each other across both axes.

Option A: (-2, 8) and (2, -8) are reflections of each other across both axes.
Option B: (5, -6) and (-5, 6) are reflections of each other across both axes.
Option C: (4, -3) and (-4, 3) are reflections of each other across both axes.

In conclusion, reflections across both axes are an essential concept in mathematics, particularly in geometry. By understanding how to identify reflections across both axes, we can solve various problems related to coordinate geometry.
