The angle between two parallel lines is zero, we can prove it by putting the value of tanθ as 0.
What is a straight line?
A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
As we know, parallel lines in geometry are co-planar straight lines that do not cross at any point. Parallel planes are planes that never meet in the same three-dimensional space. Curves that do not touch or contact each other and maintain a constant minimum distance are known as parallel curves.
We know that the angle between two parallel lines is zero degrees.
[tex]\rm tan\theta = \dfrac{m_1-m_2}{1+m_1m_2}[/tex]
tanθ = 0
m1 = m2
Thus, the angle between two parallel lines is zero we can prove it by putting the value of tanθ as 0.
