is a triangle with sides 7-7-7 a right triangle

Is 7^2 + 7^2 = 7^2 ?????

Besides, since all 3 sides are equal, it is called an equilateral triangle, which has 3 angles of 60 degrees each.

7^2=49

so the answer is no

To determine if a triangle with sides of length 7-7-7 is a right triangle, we can make use of the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides (the legs) is equal to the square of the length of the longest side (the hypotenuse).

In this case, the triangle has three sides of equal length, which means it is an equilateral triangle. In an equilateral triangle, all angles are equal, and since an equilateral triangle has three equal angles of 60 degrees each, it cannot be a right triangle.

Therefore, the triangle with sides 7-7-7 is not a right triangle.
