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.
Tangents are drawn to the circle xÂ² + yÂ² = 12 at the points where it is met by the circle xÂ² + yÂ² - 5x + 3y - 2 = 0; Find the point of intersection of these tangents. I've tried it out. Here's what I did. 1. Find the 2 points where the circles meet by solving the 2 circle equations.
