SUMMARY

Lines And Angles

  • Corresponding angles: ∠1 &∠5, ∠4 &∠8, ∠2 &∠6, ∠3 &∠7 are pairs of corresponding angles.
  • Alternate interior angles: ∠3 &∠5, ∠2 &∠8 are the pairs of alternate interior angles.
  • Consecutive interior angles: ∠2 &∠5, ∠3 &∠8, are pairs of consecutive interior angles.
  • Vertically opposite angles: in figure, ∠1 = ∠3, ∠2 = ∠4, ∠5 = ∠7 &∠6 = ∠8.
