"WebPerpendicular lines are lines that intersect at a 90-degree angle. So, for example, line ST is perpendicular to line CD. So line ST is perpendicular to line CD. And we know that they intersect at a right angle or at a 90-degree angle because they gave us this little box here which literally means that the measure of this angle is 90 degrees.

WebTo solve #1, we can create a contour_intersect function that uses a bitwise AND operation with np.logical_and () to detect intersection. The idea is to create two separate masks for each contour and then use the logical AND operation on them. Any points that have a positive value ( 1 or True) will be points of intersection.
