Lesson: Identifying and Proving Lines Parallel Using Angle Relationships

Worksheet: Identifying and Proving Lines Parallel Using Angle Relationships • 3 Questions

Q1:

Which of the following correctly defines parallel lines?

  • ATwo lines are said to be parallel if they lie in the same plane and meet at an reflex angles.
  • BTwo lines are said to be parallel if they lie in the same plane and meet at an acute angles.
  • CTwo lines are said to be parallel if they lie in the same plane and never intersect however far they are extended.
  • DTwo lines are said to be parallel if they lie in the same plane and meet at an obtuse angle.
  • ETwo lines are said to be parallel if they lie in the same plane and meet at an right angles.

Q2:

The figure shows a pair of parallel lines with a transversal drawn through them.

What name is given to the pairs of colored angles highlighted in the figure.

  • Astraight angles
  • Bcorresponding angles
  • Cexterior angles
  • Dinterior angles

What do you notice regarding the measures of two corresponding angles?

  • AThey are equal.
  • BThey are complementary.
  • CThey are supplementary.
