Seems an issue more than a feature to me. At least, the doc should reflect this behavior.
Should I open a issue on GH ?

Hi Nicolas, it seems the QgsTriangle::angles() fails to correctly return the value of angles greater than 90° deg. (Pi/2 rad.). Actually the function code strangely subtract 90 to such angles: https://github.com/qgis/QGIS/blob/dd0cd13a00998bc153c0b6519ea75038b57a6df5/src/core/geometry/qgstriangle.cpp#L397-L403 angles.append( ( a1 > M_PI_2 ? a1 - M_PI_2 : a1 ) ); angles.append( ( a2 > M_PI_2 ? a2 - M_PI_2 : a2 ) ); angles.append( ( a3 > M_PI_2 ? a3 - M_PI_2 : a3 ) ); In fact, the correct value of the angle is 90.05074766261984076 deg. and not 0.05074766261984076.
