• # question_answer How many degree are there in half a revolution? In one right angle? In one straight angle? How many right angle makes $180{}^\circ ,\,\,360{}^\circ$

Number of degrees in one complete revolution $=360{}^\circ$ $\therefore$ Number of degrees in half revolution                         $=\frac{1}{2}\times 360{}^\circ =180{}^\circ$ Number of degree in one right angle or $\frac{1}{4}$of a revolution $=\frac{1}{4}\times 360{}^\circ =90{}^\circ$ Number of degree in a straight angle                         $=\frac{1}{2}\times 360{}^\circ =180{}^\circ$ $180{}^\circ =\left( \frac{180{}^\circ }{90{}^\circ } \right)$right angles        = 2 right angles                         $360{}^\circ =\left( \frac{360{}^\circ }{90{}^\circ } \right)$ right angles         = 4 right angles.
