Please solve the below 3 questions.... 1. Show that the points (2,-1), (0,2), (2,3) and (4,0) are the vertices of a parallelogram. Also find the acute angle between the diagonals. 2. Find the equation of the line passing through the point (2,3) and at a distance of 3 units from the origin. 3. Find the perpendicular distance of the line passing through the points A(cos x, sin x) and B(cos y, sin y) from the origin.
