##### Reflection Composition

Composition of reflection in two parallel lines. Can you match the combined reflections with a translation?##### Reflection in a circle

Point A is midway between the center and the circumference of a circle. BC is the reflection of AB in the circle. What is the maximum angle of ABC?##### Maximum Angle of Reflection

Drag B to find the maximum angle of reflection. The circumcircle of ABC is the locus of all points which subtend the same angle on chord AC. In general G is inside the circumcircle and so angle AGC < angle ABC. The exception is when B=G.##### Ellipse Reflection Property

One definition of an ellipse is as the locus of points the sum of whose distance from two fixed points (the foci) is constant. This gives you a way to draw the ellipse with two pins and a piece of string. Here we relate that definition to the focal property: that light emanating from one focus reflects to the other focus.##### Reflection Clock

Press the**Reflect**button to reflect the triangle in the minute hand. Press again to reflect the result in the second hand. Can you describe the motion of the second reflected image?
