A five-pointed star, often referred to as a pentagram, has 10 angles in total. Each of the five points contributes an angle at the tip, and there are also angles formed at the intersections of the lines that connect the points. Thus, when you sum the angles at the tips and those formed internally, you arrive at 10 angles.

How many obtuse angles are there in a star?

A star, specifically a five-pointed star (pentagram), typically has 10 angles: 5 acute angles at the points and 5 obtuse angles between the points. Therefore, there are 5 obtuse angles in a standard five-pointed star. The exact number may vary depending on the design of the star, but in common geometric representations, it usually remains consistent.


What is the sum of the acute angles in a 5 pointed star?

In a regular 5-pointed star, the sum of the acute angles at each point can be calculated by considering the geometry of the star. Each point of the star forms an angle of 36 degrees at its vertex. Since there are 5 points, the sum of the acute angles is (5 \times 36 = 180) degrees. Therefore, the sum of the acute angles in a 5-pointed star is 180 degrees.


How many acute angles does a 5 pointed star have?

A 5-pointed star, specifically a regular pentagram, has 10 acute angles. Each of the star's five points forms an acute angle, and within these angles, there are additional angles created by the intersections of the lines that connect the points. Therefore, when counting both the outer and inner angles, the total comes to 10 acute angles.


What 2d shape has 5 sides all equal angles and no lines of symmetry?

There is no such shape. A 2d shape with 5 sides and all equal angles must be a regular pentagon (or a 5-pointed star if you stretch the definition of "all angles"). And a regular pentagon - or star - has 5 lines of symmetry.
