The lines must be perpendicular because a rhombus's diagonals are perpendicular. video https://cdn.kastatic.org/googleusercontent/mKYXjju71wAr3Vy6ys_yUJ5S2oSmi__H48LacOKR1o_m-z3slNSRZnh3wgHGwIef_hRrwBRCsCnImgupvwZPCUYOrQ Geometric constructions: perpendicular line through a point not on the line We can construct a perpendicular line through a point off the line.

This lesson begins with an introduction to perpendicular lines and then explores different methods for constructing them. You’ll see how to draw a perpendicular to a line at a point on the line using both a set square and a protractor. The video also covers techniques for drawing a perpendicular to a line at a point outside the line, including folding the paper and using a set square. Each method is explained in a simple and practical way, making it easy to follow along and apply in your own geometry practice.
