A geometric symbol indicating a measured or marked angle between two rays or line segments.
Examples
Basic angle measurement notation
\measuredangle ABC = 60°
Angle in a triangle with multiple angles
\text{In triangle ABC: } \measuredangle A = 45°, \measuredangle B = 60°, \measuredangle C = 75°
Geometric proof involving angles
\text{If } \measuredangle ABC \cong \measuredangle DEF \text{ then both angles are equal}
