An acute triangle.
A polygon with three acute angles is known as an acute triangle. In an acute triangle, all interior angles are less than 90 degrees. This type of triangle can have varying side lengths, making it scalene, isosceles, or equilateral, but the defining characteristic is that each angle remains acute.
Any polygon can contain acute interior angles.
An acute polygon is one whose interior angles are all acute. Only a triangle can be an acute polygon.
A 5-sided polygon, or pentagon, can have a varying number of acute angles, depending on its specific shape. However, the sum of the interior angles of a pentagon is 540 degrees. Since an acute angle is defined as an angle less than 90 degrees, a pentagon can have 0 to 4 acute angles, but typically, it may have 1 to 3 acute angles while still maintaining the overall angle sum.
A polygon, that is, a plane area bounded by any number (>2) of straight lines can have acute angles.
If its acute angles are different then it is not a regular polygon but if it has 3 equal acute angles of 60 degrees then it is a regular equilateral triangle
The only polygon with just acute angles is an acute angled triangle.
Any polygon can contain acute interior angles.
An acute polygon is one whose interior angles are all acute. Only a triangle can be an acute polygon.
That's an 'acute' triangle.
Parallelogram.
A triangle having all angles less than 90 degrees is a polygon having no parallel sides and all acute angles.
A square
A polygon, that is, a plane area bounded by any number (>2) of straight lines can have acute angles.
A triangle.
A right angle triangle
A triangle with 3 acute angles is an acute triangle. All the angles in an acute triangle are acute.
