How does the figure verify the triangle inequality theorem 4k 11 O by showing that the sides with lengths of 7 and 4 can form many possible triangles by showing that the sides with lengths of 7 and 4 can meet to form a third vertex by showing that the sides with lengths of 7 and 4 will never meet by showing that the sides with lengths of 7 and 4 will only meet when they lie on the third side O O O
