$\\pi$ radians is equal to $180^\\circ$. This means each $\\pi$ we see we can replace it with $180^\\circ$. In other words, to convert from radians to degrees we divide by $\\pi$ and multiply by $180^\\circ$.

For example, $\\displaystyle \\frac{2\\pi}{5}=\\frac{2\\pi\\times 180^\\circ}{5\\pi}=\\frac{2\\times 180^\\circ}{5}=72^\\circ$.

It is useful to memorise some of the very common angles, for example, $\\displaystyle \\frac{\\pi}{6}=30^\\circ,\\, \\frac{\\pi}{4}=45^\\circ,\\, \\frac{\\pi}{3}=60^\\circ, \\,\\frac{\\pi}{2}=90^\\circ, \\,\\pi=180^\\circ$ and $2\\pi=360^\\circ$.
