Angular Sector
In a plane, a geometric figure defined by the union or the intersection of two half-planes whose boundaries intersect at a point O called the vertex of the angular sector.
- The radian measure of a salient angular sector is the real number [latex]a\in \left[ 0,\pi \right][/latex].The radian measure of a re-entrant angular sector is the real number [latex]\left( 2\pi-a \right)[/latex] where [latex]a\in \left [ 0,\pi \right ][/latex].
- The degree measure of a salient angular sector is the real number [latex]\beta \in \left [ 0,180 \right ][/latex]. The degree measure of a re-entrant angular sector is the real number [latex]\left ( 360-\beta \right )[/latex] where [latex]\beta\in\left [ 0,180\right ][/latex].
- The gradient of a salient angular sector is the real number [latex]y \in \left [ 0,200 \right ][/latex]. The gradient of a re-entrant angular sector is the real number [latex]\left ( 400-y \right )[/latex] where [latex]y \in \left [ 0,200 \right ][/latex].
