✓

Answer

  1. A Triangle
    Solution:
    If three or more points lie on same line then they are called collinear points. A, B and C are collinear means they form a line. Point D is outside the line. Point D can be join with the end points of the line formed by points A, B, and C. For this we need total three lines to form a closed figure. A closed figure with three sides is called triangle.
