As far as I know, there is no "regular" 4 pointed star.
However, if you have a 4 pointed star, you can draw a circle through it's inner points and a second circle around its outer points. If we say that the inner circle has radius "r" and the outer circle has radius "R", that the angle, "a", of the star's points are:
a = atan(2r / (R√2 - r)
If the outer circle is twice as big as the inner circle, this becomes:
a = atan(2r / (2r√2 - r) = atan(2 / (2√2-1) = 47.5°
A 4 pointed star.
A four pointed star.
That depends on the size of the star.
A rectangle has 4 right angles whereas a regular 5 sided pentagon has no right angles.
if you mean 4 pointed star like a ninja star, there's a pretty good video showing you how here: http://foldsomething.com/origami-videos/4-point-star-ninja-throwing-star-shuriken/
A polygon with 4 right angles is a rectangle. (A square is a "regular" rectangle.)
4 such as a square
A regular square is just a square with 4 equal and parallel sides, and 4 equal right angles.
The sum of the exterior angles of a polygon equals 360.Quadrilateral has 4 exterior angles.360/4=90 for a regular quadrilateral.
There are 6 obtuse angles in a regular hexagon.no 4 okay mon
