Geometric Construction 2


From a point outside a given ellipse, construct the pair of tangents passing through the point. Also, construct the points of tangency.



Construct an animation displaying various rectangles tangent to a given ellipse.


Given two points on the same side of a straight line:
construct an ellipse tangent to the line having the two points as foci.


Given a point lying inside a triangle
construct an ellipse tangent to the three sides of the triangle having the given point as one focus.


Construct the ellipse passing through a given point with the two foci given.


Construct an animation displaying a pair of ellipses of the same size tangent to each other with one revolving around the other.


Modify the above animation so the points A, B are stationary while two ellipses are moving.
