This app allows you to experiment with an alternate construction of a hyperbola. The tracing of the perpendicular bisector of the segment between a point on a circle and a point outside the circle create a hyperbolic locus. (G-GPE 3)

This app allows you to experiment with an alternate construction of an ellipse. The tracing of the perpendicular bisector of the segment between a point on a circle and a point in the circle create an elliptical locus. (G-GPE 3)

This app allows you to experiment with the definition of an ellipse as the set of points in which the sum of the distances from two fixed points is a constant. (G-GPE 3)

This app allows you to experiment with the definition of a hyperbola as the set of points in which the difference of the distances from two fixed points is a constant. (G-GPE 3)
