The lines in the picture represent the sides and between these sides an angle of 60 degree formed option (d) is correct.
What is an angle?
When two lines or rays converge at the same point, the measurement between them is called a "Angle."
We have two sides shown in which an angle of 60 degree formed.
Here the point B is the vertex of an angle as the two lines or sides intersect at that point.
BD and BC are two sides, between these two lines an angle is formed.
Thus, the lines in the picture represent the sides and between these sides an angle of 60 degree formed option (d) is correct.
