The answer depends on what instruments you have available. If you have a protractor, draw an inward facing 60 degree angle from each end of the line segment, and extend the lines until they meet.
No.
Yes in equilateral triangle.
Yes and it will have 3 equal sides
No but it is possible for it to be an isosceles triangle with angles of 45, 45 and 90 degrees
An equilateral triangle that has a perimeter of 57 feet has three equal sides of 19 feet.
No.
Not in this Universe.
No.
Yes in equilateral triangle.
Yes and it will have 3 equal sides
It could have (it would then be an isosceles, or even equilateral triangle) but it does not have to.
A triangle with three equal sides and angles is an equilateral triangle. It could also be called an equiangular triangle.
yo creo que no es la respuesta

no. A triangle has total 180 degrees. An equilateral triangle requires all three angle measures to be the same, so every angle HAS to be equal to 60 degrees. A right triangle has 1 90 degree angle and 2 45 degree angles, so it can never be an equilateral triangle.
