Yes. Triangles can be constructed with sides of any length as long as the sum of any two of the sides is greater than the remaining side (so you couldn't for example have a triangle with sides of lengths 5, 2, and 1, since 5>1+2).
yes it is possible.
yes.
No, it is not possible to build a triangle with side lengths of 8, 7, and 15. According to the triangle inequality theorem, the sum of the lengths of any two sides must be greater than the length of the third side. In this case, 8 + 7 equals 15, which is not greater than 15, so these lengths cannot form a triangle.
No, it is not possible to build a triangle with side lengths of 3, 3, and 9. According to the triangle inequality theorem, the sum of the lengths of any two sides must be greater than the length of the third side. In this case, 3 + 3 is not greater than 9, so these side lengths cannot form a triangle.
In a triangle, if all of the angles are 60 degrees, then all three sides of the triangle are equal to each other. Basically, if the angles are equal than the sides must be equal. This kind of triangle is called an equilateral triangle.

True and it will be an equilateral triangle
they all have to be congruent
