In learner-centred methods, the teacher/instructor is both a teacher and a learner at the same time. In the words of Lawrence Stenhouse, the teacher plays a dual role as a learner as well âso that in his classroom extends rather than constricts his intellectual horizonsâ.
Two-point perspective has one set of lines parallel to the picture plane and two sets oblique to it. Parallel lines oblique to the picture plane converge to a vanishing point, which means that this set-up will require two vanishing points. Walls in 2-point perspective, converging toward two vanishing points.
The point where the x and y axes intersect is called the origin. The origin is located at zero on the x axis and zero on the y axis. Locating Points Using Ordered Pairs. We can locate any point on the coordinate plane using an ordered pair of numbers like the example shown here, the ordered pair 4 and 2 (point P). We call the ordered pair the coordinates of the point.
