What are the angles of a 4 point star?
If there are 4 points, we can only have a square, so the angle is 90 degrees. If there are 5 points, we can have a pentagon, where the angle is 108 degrees; or we can have a “star” in the question, where the angle is 36 degrees.
What are the angles in a 5 sided star?
The 5-pointed star has a 36° interior angle at each point (vertex). So, the exterior angle at each point is 360°- 36° = 324°.
What are the angles of a wooden star?
The first thing to notice is that the angles that make up the middle of the star have to total 360 degrees. Since a star has five points, if we wanted all the points to be the same, the center angles would be 72 degrees (360/5=72).
What are the angles of a 6 point star?

How many vertices does a 2d star have?
A regular star pentagon, {5/2}, has five corner vertices and intersecting edges, while concave decagon, |5/2|, has ten edges and two sets of five vertices.
Do all Triangle angles equal 180?
If a triangle is neither isosceles nor right, we will call it a generic triangle. A piece of trivia that is true for all triangles: The sum of the three angles of any triangle is equal to 180 degrees.
Which is the correct angle for a 5 point star?
These are the angles from alternating sides of the piece cut. It takes 10 equal pieces to make a 5 point star. For a pentagon it takes 5 pieces to form the shape. Take the 72° angle and divide in half equaling 36°. Because there are only 5 pieces, 10 cuts to make a pentagon. The 36° angle is applied from the same side of the piece.
What is the sum of angles in a star?
You can see an animation of that here: star pentagon angle sum animation. While that is not a proof, it suggests an answer of 180 degrees, which might give you the idea to think about half of a circle or the sum of angles in a triangle. These concepts can be used to prove the result. There is a wonderful proof for a regular star pentagon.
How many degrees are in a pentagram star?
In a regular pentagram (5-pointed star), the angle in each point is 36 degrees, so the angles in all five points sum to 180 degrees:
How many equal pieces are needed to make a 5 point star?
For five point star because there are 20 cuts, the miter angles are 72° & 36° at the ends of each piece. These are the angles from alternating sides of the piece cut. It takes 10 equal pieces to make a 5 point star. For a pentagon it takes 5 pieces to form the shape.
