Two parallel lines Land Ly undergo a rigid transformation. For which scenario are the transformed lines L and L', always parallel? O Li is translated 4 units down, and L2 is rotated 90' clockwise about the origin.
O L is translated 2 units to the right, and L2 is translated 2 units to the left.
O Li is rotated 90 clockwise about the origin, and L, is rotated 180° about the origin.
O L is reflected across the y-axis, and L2 is translated 3 units up.

Consider the following geometry problems in 3-space enter t or f depending on whether the statement is true or false. (you must enter t or f -- true and false will not work.) f equation editorequation editor 1. a plane and a line either intersect or are parallel t equation editorequation editor 2. two planes parallel to a third plane are parallel f equation editorequation editor 3. two lines either intersect or are parallel f equation editorequation editor 4. two planes orthogonal to a third plane are parallel f equation editorequation editor 5. two planes orthogonal to a line are parallel f equation editorequation editor 6. two planes either intersect or are parallel f equation editorequation editor 7. two lines orthogonal to a third line are parallel t equation editorequation editor 8. two lines parallel to a third line are parallel t equation editorequation editor 9. two planes parallel to a line are parallel f equation editorequation editor 10. two lines parallel to a plane are parallel f equation editorequation editor 11. two lines orthogonal to a plane are parallel
