Not necessarily. But a regular triangle must be acute angled.
Regular, Acute, and Equilateral * * * * * Regular and Equilateral are correct but not Acute. An acute triangle with angles of 50,60 70 degrees for example, is not regular. An equiangular triangle is the third possible name.
Yes. An acute triangle has three acute angles so that would make it a regular polygon with congruent sides.
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

A right triangle has an acute and right angle.
An obtuse triangle or an isosceles triangle if the 2 acute angles are equal in size
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.
The only polygon with just acute angles is an acute angled triangle.
