Noun. 1. ellipse-a closed plane curve resulting from the intersection of a circular cone and a plane cutting completely through it; the sums of the distances from the foci to any point on an ellipse is constant. oval. conic, conic section - (geometry) a curve generated by the intersection of a plane and a circular cone.
The Ellipses Gizmo starts by relating the formula of an ellipse to the formula of a circle, which is a special type of ellipse. Students then explore the Pythagorean relationship, which allows the position of the foci to be determined. In addition, the Gizmo helps make sense of the definition of an ellipse, which can be a tricky one. An ellipse is a curve created by moving a point so that the sum of its distances from two fixed points (the foci) is constant. Thatâs tough to picture, but the draggable purple point in the Gizmo illustrates it nicely. It also is a perfect lead-in to the hands-on activity of actually drawing an ellipse using a compass, a loop of string, and two push pins.
