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.
Check their y-intercepts (where they cross the y-axis) as well as their slope: For y = 3x + 2: the slope is 3, and y-intercept is 2. For y â 2 = 3x: the slope is 3, and y-intercept is 2. In fact they are the same line and so are not parallel. Two lines are Perpendicular if they meet at a right angle (90Â°).
