  1. Geometry 4 Level 1

  2. Are the lines parallel?

  3. Corresponding Angles are equal

  4. Corresponding angles a a

  5. Vertically opposite angles are equal a a a

  6. Alternate angles are equal a a a

  7. Are these lines parallel?

  8. a + c = 180 ( )

  9. a + c = 180 ( ) These must add to 180

  10. a + c = 180 (co-interior angles)

  11. Are these lines parallel?
