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
