Draw a line l and take two two points A and B on it. Through A & B, draw linesl2andl3 perpendicular to l1. On l2, mark a point C at a distance 4 cm from l1and draw a line l4 parallel to l1 through C. If l4intersects l3 at D, what type of quadrilateral is ABDC? Can you please solve this, please? I want its solutions fast.
