Question 1.
What is the reflection of the point (5, 10) over the x-axis?
Show hintHide hint
Remember to negate the y-coordinate.
Question 2.
What is the reflection of the point (-3, 4) over the y-axis?
Show hintHide hint
Negate the x-coordinate!
3Question 3.
What happens to the y-coordinate of a point when it is reflected over the x-axis?
- It remains the same
- It becomes negative
- It becomes doubled
Show hintHide hint
Think about the direction it’s flipping.
4Question 4.
True or False: Reflecting the point (5, -3) over the y-axis gives you (5, -3).
- True
- False
Show hintHide hint
Remember what happens to x-coordinates during reflection.
Question 5.
Given a rectangle with corners at (1, 1), (1, 3), (4, 1), and (4, 3), find the coordinates of the rectangle after reflecting it over both the x-axis and then the y-axis.
Show hintHide hint
Remember to reflect one axis at a time.
Question 6.
Create an algorithm that takes any point and reflects it over both axes and returns the new coordinates.
Show hintHide hint
Look how reflection affects each coordinate.
