what polygon has seven sides and seven angles
Heptagon is one of the types of polygon which has 7 sides and seven angles. A heptagon may be a regular or an irregular in shape. A regular heptagon has 7 equal sides and 7 angles of equal measure. An irregular heptagon does not have all the angles and sides equal. It is irregular in shape.A regular heptagon is shown in the figure given below.
If heptagon is regular, then all sides and all angles are equal and the sides meet at an angle of $\frac{5\pi}{7}$ radians. Heptagon Sides = 7. Given below are some heptagon facts: Interior angle of a polygon is measured with the help of a general formula which is given by $\frac{180n - 360}{n}$.
