This example demonstrates the properties of parallel and perpendicular lines in the coordinate plane. Through interactive exploration, students can discover key properties of parallel and perpendicular lines. The construction uses GeoGebra objects such as points, lines, and slope. Suitable for students in middle school and above learning coordinate geometry.

AI Drawing Prompt Reference
Draw two parallel lines and a line perpendicular to one of them in the coordinate plane to demonstrate the properties of parallel and perpendicular lines. Start by placing two points, then draw two lines using these points and a point on the perpendicular line. Calculate the slope of one line and use it to draw another line perpendicular to it, revealing the geometric relationship between parallel and perpendicular lines.
