Yes. If the sum of the length of the two smaller sides are greater than the length of the larger side and none of the lengths of any of the sides equals 0, then it is a triangle.
It is not, however, an equilateral triangle or right triangle (that would be 5, 4, 3), though it is an isosceles triangle.

Why does a triangles have three sides and three angles?
That is the definition of a triangle. If it did not have three sides it would not be a triangle. If it did not have three angles, it would not be a triangle.
Is it possible to build a triangle with side lengths of 7 6 and 9?
Yes It is. Try it. All the sides of a triangle don't have to of equal length. -Cody Dunn Also, as long as the sum of any two sides exceeds the length of the third side, the three sides can build a triangle. This is false!
What would you call a triangle when all three sides are congruent?
When all three sides of a triangle are congruent, it is called an equilateral triangle.
Why the following triangle with sides 2.5 6.5 and 6 is a right angle triangle or not?
It is a right angle triangle because it complies with Pythagoras' theorem.
Why are scalene triangles and equilateral triangles different?
A scalene triangle has three unequal sides, an equilateral triangle has three equal sides. An isosceles triangle has two equal sides. Because with a scalene triangle only two sides are equal but with a equilateral triangle that would mean all sides are equal. (scalene = 2 sides & equilateral = all sides equal)
