In a regular star polygon, each interior angle is 180 degrees multiplied by (1 - 2/n), where n is the number of points on the star. An obtuse angle is any angle greater than 90 degrees but less than 180 degrees. Therefore, in a star polygon, there will be obtuse angles if the number of points on the star is such that the interior angle is greater than 90 degrees but less than 180 degrees. The number of obtuse angles in a star polygon will depend on the specific number of points and the resulting interior angles.
A rhombus have 2 obtuse angles
A regular star with n points has 2 interior angles of which n are acute and n are reflex.
There are 3 obtuse angles in a heptagon.
One and the two others are acute angles
It depends on they type of arrowhead you have. If it is a arrowhead in the shape of a directional arrow, there are no obtuse angles. The most possible obtuse angles is 1.
the answer is 5 each tip of the star is a acute angle and each angle on the inside of the star is an obtuse angle. there are 5 obtuse angles and no right angles.
