Understanding Perpendicular Lines
In geometry, perpendicular lines are lines that intersect at a right angle (90 degrees). If a line has a slope 'm', then a line perpendicular to it has a slope of '-1/m', provided m is not zero. For a horizontal line (slope = 0), a perpendicular line is vertical and its equation is of the form x = constant.
How to use this tool:
- Enter the slope of the given line.
- Enter the x and y coordinates of a point that the perpendicular line passes through.
- Click 'Calculate' to find the equation of the perpendicular line.
- The equation and an interactive graph visualizing both lines will be displayed.
- Use the 'Copy Equation' button to copy the equation for your use.
