No, any polygon.
1260 degrees
They have the same measures.
Nope ! For example - the sum of the angles in a triangle is 180, while those of a square (or rectangle) are 360.
180*2
The sum of the exterior angles of all polygons is 360 degrees.
No, any polygon.
In a tessellation, the angle sum around a vertex depends on the type of polygons used in the tessellation. For regular polygons, the angle sum around a vertex is always 360 degrees. This is because each interior angle of a regular polygon is the same, so when multiple regular polygons meet at a vertex in a tessellation, the angles add up to 360 degrees.
360 degrees. (All polygons have an exterior angle sum of 360 degrees.)
1260 degrees
They have the same measures.
angle sum of a parallelogram
Nope ! For example - the sum of the angles in a triangle is 180, while those of a square (or rectangle) are 360.
180*2
All polygons with four angles (quadrilaterals) have a inner angle sum of 360 degrees.
Yes, if you interpret some of the exterior angles as having negative measure.
Only convex man, if the angle is concave it would not be 360 degree.
