How many triangles exist with the given side lengths? 4m, 4m, 7m

There are 0 triangles that can be formed with side lengths 4m, 4m, and 7m. In order for a triangle to be formed, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

In this case, the sum of the lengths of the two 4m sides is 8m, which is not greater than the length of the 7m side. Thus, no triangle can be formed with these side lengths.

8 > 7 !!!!

Apologies for the oversight. You are correct.

A triangle can be formed with side lengths 4m, 4m, and 7m. In this case, it would be a scalene triangle with one side of length 7m and the other two sides of length 4m.

There is only 1 triangle that can be formed with side lengths 4m, 4m, and 7m.
