yes, by definition it has to be. Equilateral triangles have only one shape or design. I interpret your question asking would it bisect if a dotted line was drawn down from the altitude or the joining point of two sides.
An equilateral triangle.
Yes.
Yes, because an equilateral triangle is always acute.
sometimes, but not always
It always is because it has 3 equal angles of 60 degrees
An equilateral triangle.
No, never in plane geometry.
Yes. Every triangle is a polygon.
No, an equilateral triangle always has 3 equal angles (each angle is 60°)
no, it is impossible an angle of an equilateral triangle is always 60 degrees it can't be 90 degree
An isosceles triangle has at least two congruent sides. An equilateral triangle has three congruent sides. So, an equilateral triangle is a special case of isosceles triangles. Since the equilateral triangle has three congruent sides, it satisfies the conditions of isosceles triangle. So, equilateral triangles are always isosceles triangles. Source: www.icoachmath.com
