An acute angled triangle.
The exterior angles of a 15 sided shape add up to 360 degrees
A regular pentagon has no acute angles. It is possible to draw a pentagon (five sided polygon) where four of the internal angles are acute.
A regular 5 sided pentagon has exterior acute angles and interior obtuse angles each of 72 degrees and 108 degrees respectively
52 angles.
An acute angled triangle.
An acute triangle.
The sum of the angles in the 33 sided shape is 5,580 degrees
It could be an irregular 5 sided pentagon providing that its 5 inteior angles add up to 540 degrees
A triangle.
The exterior angles of a 15 sided shape add up to 360 degrees
A regular pentagon has no acute angles. It is possible to draw a pentagon (five sided polygon) where four of the internal angles are acute.
The interior angles of a 24 sided shape add up to 3960 degrees
A regular six-sided hexagon has no interior acute angles, but it does have six interior obtuse angles, each measuring 120 degrees
A regular 5 sided pentagon has exterior acute angles and interior obtuse angles each of 72 degrees and 108 degrees respectively
52 angles.
There is no three-sided shape with two obtuse angles, because the three interior angles of a three-sided shape, which is a triangle, add up to 180 degrees, and two obtuse angles would be over 180 degrees.
