Triangle ABC is an equilateral triangle if and only if the lengths AB, AC & BC are all equal and the angles ∠ABC, ∠ACB & ∠CAB are all equal (to 60o).
A triangle is the same as a equilateral triangle because a equilateral triangle is a triangle but it is congruent on all sides
No, an equilateral triangle has to be equiangular, but an equiangular triangle does NOT have to be equilateral
That depends on what is meant by length of AD but the 3 sides of an equilateral triangle are all equal in lengths.
An oxymoron. An equilateral triangle cannot be obtuse; an obtuse triangle cannot be equilateral.

Are isosceles triangle sometimes an equilateral triangle
there is not one because a equilateral triangle is one triangle so the ansew is equilateral triangle
No, an equilateral triangle can not be an obtuse triangle. All angles in an equilateral triangle are 60o. An obtuse triangle has 1 angle that is greater than 90o.
Where the side of the equilateral triangle is s and the radius of the inscribed circle is r:s = 2r * tan 30° = 48.50 cm
The equilateral triangle.
It is an equilateral triangle
The contrapositive would be: If it is not an isosceles triangle then it is not an equilateral triangle.
