About This Quiz & Worksheet

Parallel lines are equidistant from one another and will never intersect. You can determine whether lines are parallel by utilizing a number of mathematical assumptions, such as the various kinds of angles involved in an equation. A basic understanding of geometry will help you be successful on this quiz.

Quiz & Worksheet Goals

To demonstrate your competence of parallel lines, you will be quizzed on the following:

  • Angles (corresponding, supplementary, alternate interior, and alternate exterior)
  • The equations used for angles to identify parallel lines
  • Visual examples where you will utilize all of the above

Skills Practiced

  • Knowledge application - use your knowledge to accurately identify parallel lines
  • Distinguishing differences - compare and contrast the various angles used to determine parallel lines
  • Problem solving - use acquired knowledge to solve geometry problems and identify parallel lines

Additional Learning
