Two Diverging Lines With Their Intersect Inside A Circle
Number of solutions: 8
GeoGebra construction
Steps
- Draw the perpendicular line f to the given line p2 so that it passes through the centre of the given circle (E). The points G and J are the intersections of the perpendicular line f with the given circle.
- Draw the perpendicular line g to the given line p1 so that it passes through the centre of the given circle (E). Points H and I are the intersections of the perpendicular line g with the given circle.
- Draw 4 lines where each line passes through one of the constructed intersections. Each of these lines is also perpendicular to either line f or g, depending on which of these the constructed intersection lies on.
- The intersections of these 4 constructed lines are named K, L, M, and N.
- Name the intersection of the given lines O.
- Construct the line OL and name it l.
- Name the intersections of the given circle and line l P and Q.
- Construct the axes of the angles between the given lines.
- Construct the line EP. Name the intersection of the line EP and the angle axis S1. The S1 is the center of the first circle of the solution.
- Construct a circle k1 that is centered at S1 and passes through point P. k1 is the first circle of the solution.
- Construct the line EQ. Name the intersection of the line EQ and the axis of the angle S2. The S2 is the center of the second circle of the solution.
- Construct a circle k2 that is centered at S2 and passes through the point Q. k2 is the second circle of the solution. Repeat steps 6-12 for points M, N, and K. Each of these repetitions gives us 2 solution circles.
