The only polygon with just acute angles is an acute angled triangle.
A right angle triangle
In general, a regular polygon is not required for a normal tetrahedron.An equilateral triangle is required for a regular tetrahedron.
A triangle is a polygon. It can be regular or irregular. If it's regular, then all three sides are the same length, and it's called an "equilateral triangle". If all three sides aren't the same length, then it's an irregular polygon.
It is irregular as not all the sides have the same length.
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.
Yes. An acute triangle has three acute angles so that would make it a regular polygon with congruent sides.
No. All interior angles of the regular hexagon are 120 degrees. The only regular polygon with acute angles is the equilateral triangle (60 degrees)
A triangle in general is just a polygon. An equilateral triangle is a regular polygon.
A triangle may or may not be a regular polygon. Let's look into things.First, a triangle is a polygon. All triangles are polygons. To be a regular polygon, the polygon must have equal sides. If the triangle has sides of equal length, then that triangle is an equilateral triangle and a regular polygon. If the triangle doesn't have sides of equal length, then it isn't a regular polygon. But in any case, the triangle is a polygon.
An acute triangle.
Yes
Yes
An acute polygon is one whose interior angles are all acute. Only a triangle can be an acute polygon.
A triangle is a polygon. An equilateral triangle is one in which all the sides are the same and all the angles are the same. Then it is a regular polygon.
The acute triangle.
An equilateral triangle is one in which each angle is 60 degrees. It is, therefore, an acute triangle.
