If your triangle has the sides of 4, 5, and 6. Is the triangle a right triangle, explain?

All right triangles follow Pythagorean theorem. (a² + b² = c² )This triangle is not a right triangle because the sum of both sides squared doesn't equal to the sum of the hypotenuse squared. For example 5²+ 4² 6².

But there is also a rule to finding out what type of triangle it is.

Right triangle = a² + b² = c²

Obtuse Triangle = a² + b² > c²

Acute Triangle = a² + b² < c²

But if the sum of the two sides are less than the hypotenuse its not a triangle.

Not a Triangle = a + b < c
