I'm on a time which of the following represents a rotation of △pqr, which has vertices p(−2,4), q(−3,−9), and r(4,−2), about the origin by 180°? p (2, −4) q (3, 9) r (−4, −2) p (2, −4) q (−9, −3) r (−4, −2) p (2, −4) q (3, 9) r (−4, 2) p (−4, −2) q (9, −3) r (2, 4)

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
