Transcript

  • 1. Parallel Lines & Transversals By Victoria Miles
  • 2. Activator Problem Solution: m<1 = 60 o . (given) m<3 = m<5 =m<7 =60 o m<2, m<4, m<6, m<8 = 120 o .
  • 3. Perpendicular and Parallel Lines BrainPop MOVIE click here Mr. Vaugh’s flash movie click here
  • 4. Congruent Angles
  • 5. More Definitions <ul><li>Perpendicular lines are lines that intersect at right angles. </li></ul><ul><li>Parallel lines are lines that never intersect. </li></ul><ul><li>A transversal is a line that intersects two or more lines. </li></ul>
  • 6. Special Types of Angles Click here to interact:
  • 7. Vertical Angles
  • 8. Corresponding Angles
  • 9. Alternate Interior Angles
  • 10. Summary <ul><li>Parallel lines are lines that never meet. </li></ul><ul><li>Perpendicular lines meet at right angles. </li></ul><ul><li>A transversal is a line that intersects 2 or more (parallel) lines. </li></ul><ul><li>Parallel lines cut by a transversal form 8 angles . </li></ul><ul><li>Pairs of angles will be either congruent or supplementary . </li></ul><ul><li>Special pairs of angles will be congruent . </li></ul><ul><ul><li>Vertical angles </li></ul></ul><ul><ul><li>Corresponding angles </li></ul></ul><ul><ul><li>Alternate Interior Angles </li></ul></ul>Interactive math dictionary
  • 11. Your turn! Find the measure of the other angles. 105 o
  • 12. Try this one! Solve for a, b, c, d, x, y and z x 65 o y + 20 z a - 10 b 5 c d ÷ 2
  • 13. More special angles… <ul><li>http://www.shodor.org/interactivate/activities </li></ul><ul><li>Sources </li></ul><ul><li>http://www.mathsisfun.com </li></ul><ul><li>http://www.algebra.com </li></ul><ul><li>http://www.teachers.ash.org.au/jeather/maths/dictionary.htm l </li></ul>
