A polygon can be any one of them.
A right triangle.
An acute triangle.
Yes
An acute polygon is one whose interior angles are all acute. Only a triangle can be an acute polygon.
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 acute triangle.
An equilateral triangle is one in which each angle is 60 degrees. It is, therefore, an acute triangle.
it can be a triangle that is right, acute, or obtuse
A regular polygon is one which has all equal sides. But in an isosceles triangle, only 2 sides are equal. The third side has a different measure.Thus an isosceles acute triangle is not a regular polygon.
A polygon can be any one of them.
The only polygon with just acute angles is an acute angled triangle.
Yes. An acute triangle has three acute angles so that would make it a regular polygon with congruent sides.
