Diagram Showing the Relative Sizes of Triangle OAP and OAP'

This diagram is intended to show the relationship between the two triangles, OAP and OAP'. They have the same internal angles and are isosceles, and are nested within each other in the diagram. The sliders can be used to change the values of the radius and OP, allowing us to see its effect on the relative size between the two triangles. This diagram is made by Vikesh Ajith, a student at School of The Arts Singapore.
