Question 1.
What does reflection over the x-axis do to the point (3, 4)?
Show hintHide hint
Think about what happens to the y-coordinate.
Question 2.
What is the matrix for reflecting a point over the x-axis?
Show hintHide hint
Recall the transformation rules.
3Question 3.
What does reflecting a point over the x-axis do to its coordinates?
- It changes the x-coordinate
- It changes the y-coordinate
- It does not change any coordinates
Show hintHide hint
Think about symmetry concerning the x-axis.
4Question 4.
True or False: The transformation matrix for rotation around the x-axis has no effect on the x-coordinate.
- True
- False
Show hintHide hint
Refer back to how rotation is defined.
Question 5.
A point A(2, 3, 4) is reflected over the x-axis and then rotated 180 degrees about the x-axis. Determine the final coordinates.
Show hintHide hint
Apply transformations sequentially.
Question 6.
Given a point at (1, 2, 3), derive its transformation if it's reflected over the x-axis and then scaled by 2.
Show hintHide hint
Consider how each transformation modifies the coordinates.
