How many triangles exist from the given lengths 4m 4m and 7m?

Answer 1

With side lengths of 4m, 4m, and 7m, only one triangle can be formed. This is an isosceles triangle, where two sides are equal (4m each) and the third side is different (7m). The triangle inequality theorem confirms that the sum of the lengths of any two sides must be greater than the length of the third side, which holds true in this case. Therefore, exactly one triangle exists with these lengths.
