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.
No.
Not in this Universe.
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.
yo creo que no es la respuesta
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.
Yes and it would be an equilateral triangle.
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.
Yes, actually it has to be. The only type of triangle with even sides is an equilateral triangle, but all of the angles of an equilateral are 60 degrees, because everything is equal and 180(total degrees within a triangle)/3(number of angles)=60(degrees per angle of an equilateral).
