Parallel and Perpendicular Lines
Parallel lines are lines that never intersect, while perpendicular lines are lines that intersect at a right angle (90 degrees).
Identifying Parallel and Perpendicular Lines: Parallel And Perpendicular Lines Worksheet Answers Key
Examples of parallel lines include the sides of a rectangle, while examples of perpendicular lines include the sides of a square.
Parallel lines have the same slope, while perpendicular lines have slopes that are negative reciprocals of each other.
Geometric Relationships between Parallel and Perpendicular Lines
When a transversal intersects two parallel lines, the alternate interior angles are congruent and the corresponding angles are supplementary.
When a transversal intersects two perpendicular lines, the vertical angles are congruent and the adjacent angles are supplementary.
Applications of Parallel and Perpendicular Lines
Parallel and perpendicular lines are used in architecture to create symmetry and stability, and in engineering to create structures that can withstand forces.
In design, parallel and perpendicular lines can be used to create visual interest and to guide the viewer’s eye.
