To find the area of the triangle with vertices A(1, 1, 2), B(2, 3, 5), and C(1, 5, 5), we can use the vector method. The area of the triangle can be calculated using the formula: \[ \text{Area} = \frac{1}{2} \left| \vec{AB} \times \vec{AC} \right| \] where \(\vec{AB}\) and \(\vec{AC}\) are the vectors from point A to points B and C, respectively. ...
