    Ti Nspire, measurement angle help

    Hi, I am teaching True Bearings atm, and was wondering if I can use the measurement->angle function, to measure angles past 180 degrees, ie, 180-360 degrees, reflex angles?

    eg, bearing SW is T(180+45)=T225 degrees.

    If anyone knows how to do this please reply asap.

    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.
