How to apply a reflection over the x axis ex 1

The video tutorial explains how to reflect a figure over the X axis. It begins by identifying the X axis as the line of symmetry and demonstrates the process using points A, B, and C. The key concept is to take the opposite of the Y coordinate while keeping the X coordinate unchanged. The tutorial concludes by summarizing the reflection process and providing examples.

What is the first step in reflecting a figure over the X-axis?

• Translate the figure horizontally

• Find the line of symmetry

• Identify the Y-axis

• Rotate the figure 90 degrees

When reflecting a point over the X-axis, what happens to the Y-coordinate?

• It doubles

• It changes to its opposite sign

• It remains the same

• It becomes zero

If point A is at (6, 3), what will be the coordinates of A' after reflection over the X-axis?

• (3, 6)

• (-6, 3)

• (6, -3)

• (-3, -6)

Which of the following statements is true about the reflection of a point over the X-axis?

• Both X and Y coordinates change sign

• Only the X coordinate changes sign

• Neither coordinate changes sign

• Only the Y coordinate changes sign

What remains unchanged when a point is reflected over the X-axis?

• The Y-coordinate

• The X-coordinate

• Both coordinates

• The distance from the origin
