Question

The interior angle of a regular polygon IS 180°.find the value if its exterior regular polygon

Answer 1

Answer:

Sum of exterior angle is $360^0$

Value of each exterior angle is $120^0$

Step-by-step explanation:

Sum of interior angles of a polygon with n sides $=(n-2)\times180$

Here

$(n-2)180=180\\\\n=3$

Hence the polygon is triangle

Sum of exterior angle is $360^0$

Sum of one exterior angle

$=\frac{360}{3} \\\\=120^0$
