Each interior angle measures 128.57 degrees rounded
Each exterior is 360/7 = 51.4 degrees to the nearest tenth
A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.
If the measure of an interior angle of a regular polygon is 140o, the polygon is a nonagon (sometimes called an ennagon) having 9 sides.
A pentagon (five sided regular polygon) has interior angles of 108°.
A regular pentagon (5 sides)
Each exterior angle will measure 360/18 = 20.0 degrees
Only if the polygon is a regular quadrilateral.
a "regular" polygon
A regular polygon
Each exterior is 360/7 = 51.4 degrees to the nearest tenth
A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.
That would be a regular polygon.
A regular polygon.
Only if the polygon is "regular".
If the measure of an interior angle of a regular polygon is 140o, the polygon is a nonagon (sometimes called an ennagon) having 9 sides.
Only when the polygon is a regular convex polygon. Such as an equilateral triangle, or a square, or a regular pentagon.
A 13 sided regular polygon
