What theorems (about kites) are dynamically illustrated below?
(Feel free to move its white vertices anywhere you'd like!)
Theorems:
The non-vertex angles are congruent in a kite.
One diagonal of a kite bisects the vertex angles.
One diagonal of a kite bisects the other diagonal.
The diagonals of a kite are perpendicular.
Also note that this applet also illustrates the isosceles triangle theorem: If two sides of a triangle are congruent, then the angles opposite those sides are congruent!
