The angles demo allows you to dynamically calculate the angle that is formed when two straight lines meet at a shared endpoint. It demonstrates the ease at which JointJS can be used to perform complex calculations while displaying the result in your diagram applications.
Demo instructions
Drag the rectangle shapes to see the angle values change dynamically. Click on the elements and links to display tools which allow you to increment angle size, rotate elements, and change angle direction.
