The answer would be C. The triangle in question is NOT a right triangle.


For one thing, remember that a right triangle has a HYPOTENUSE, which is the LONGEST side. This shows that not all the sides has the same length. Also, remember the Pythagorean theorem:


c² = a² + b²


This means that they cannot all be equal.


If a triangle has 3 equal sides, then the triangle is an equilateral triangle.
