The Measure angle in point function allows you to measure the angle in points on all sizes. This function has only one step: Select element. After the step is completed, the result will be a measurement done between the tangents of the selected point. The measurement will be displayed in the Context options area for all sizes at once and with the base size marked in yellow. By default, the measurement is performed in the interior of the shape, but you can change the measurement direction, switching it to the exterior by clicking on the Invert option from Context option.
Just like in the case of the direct measurement, you can opt for showing the delta or the offset between consecutive sizes.
