Construction Of Parabola By An Eccentricity Method Engineering In this video, i have explained how to draw a parabola by the eccentricity method. also, i have explained how to draw a tangent and a normal to the parabola . This video demonstrates step by step, the construction of parabola by eccentricity method. here, a parabola is constructed for this objective:to construct a. Steps for parallelogram method. q.1: draw a parabola of base 100 mm and axis 50 mm if the axis makes 70° to the base. draw the base rs = 100 mm and through its midpoint k, draw the axis kv = 50 mm, inclined at 70° to rs. draw a parallelogram rsmn such that sm is parallel and equal to kv. Parabola directrix focus method solution steps: 1.locate center of line, perpendicular to ab from point f. this will be initial point p and also the vertex. 2.mark 5 mm distance to its right side, name those points 1,2,3,4 and from those draw lines parallel to ab. 3.mark 5 mm distance to its left of p and name it 1.
