Exercise 1 In each of the three coordinate planes ( xy, xz, yz) construct a square with a side length 15 whose edges lie on the positive sides of the coordinate axes.Color these squares in red, blue and green. Construct a cube for which the constructed squares are faces, and translate it for the vector a = -20i-20j-5k.Upper face of the cube color red, front face blue, and right face green. Drawn objects show in the top, front, right view and axonometry. |
