Both Points In A Circle, One Is The Centre
Number of solutions: 2
GeoGebra construction
Steps
- Given is the circle c, inside of which lie the points A and B. A lies in the centre of c
- Construct the perpendicular bisector of AB, f. The resulting circles' origins will lie on it.
- Construct a line parallel to f that goes through the point B, g. The points where g intersects c shall be named C and D
- Construct the perpendicular bisectors of BC (h) and BD (i). The points where they intersect f shall be named F and E, respectively.
- Draw the circles d and e:
- d has E as its origin, goes through the points A and B, the point of tangency with c is D
- e has F as its origin, goes through the points A and B, the point of tangency with c is C
