# Ti Nspire, measurement angle help

From what I remember from the TI N-spire, the interface is very similar to Geometer's Sketchpad. In GSP you can't measure a reflex angle directly (it's about the only major flaw to the software), but you CAN measure the corresponding acute/obtuse angle, and then have the calculator subtract this from $\displaystyle 360^{\circ}$ to measure the reflex angle.
