Please make sure that Java is installed and active in your browser. This will enable you to drag (left mouse button) and change the constructions. 

geometry: angles & lines Euclidian geometry: circle
vertical opposite angles

line through centre and midpoint of chord
angles on a straight line line from centre perpendicular to chord
  angle at the centre and circumference
geometry: parallel lines angle on diameter of circle
corresponding angles angles at circumference in same segment
alternate angles cyclic quad: equal angles
co-interior angles opposite angles of cyclic quad
  cyclic quad: opposite angles
geometry: triangles exterior angle of cyclic quad
sum of interior angles tangent and radius
exterior angle & opposite interior angle perpendicular line to tangent
Pythagoras theorem tangents from same point
Isosceles and equilateral triangles angle between tangent and chord
   
geometry: quadrilaterals  
trapezium  
parallelogram  
rectangle  
square  
kite  
rhombus
