Study Notes
Parallel and Perpendicular Lines
- Parallel lines are lines that never intersect, no matter how far they are extended.
- The defining characteristic of parallel lines is that they have the same slope.
Perpendicular Lines
- Perpendicular lines are lines that intersect at a 90-degree angle.
- A key characteristic of perpendicular lines in geometric construction is that they form a 90-degree angle.
Geometric Construction
- The primary purpose of geometric construction is to create geometric shapes using only a compass, straightedge, and pencil.
- A tool commonly used in geometric construction is a straightedge.
Perpendicular Bisector
- A perpendicular bisector is a line that divides a line segment into two equal parts at a 90-degree angle.
- The defining characteristic of a perpendicular bisector is that it bisects a line segment at a 90-degree angle.
- A perpendicular bisector differs from a parallel line in that a perpendicular bisector intersects a line segment, while a parallel line never intersects another line.
- The primary purpose of a perpendicular bisector in geometric construction is to divide a line segment into two equal parts.
