## FAQs on Angle Between two lines Video Lecture - Mathematics (Maths) Class 11 - Commerce

 1. What is the formula to calculate the angle between two lines?
Ans. The formula to calculate the angle between two lines is given by the equation: θ = tan^(-1) |(m2 - m1)/(1 + m1m2)| where m1 and m2 are the slopes of the two lines.
 2. Can the angle between two lines be negative?
Ans. No, the angle between two lines is always measured as a positive value. However, the direction of the angle can be clockwise or counterclockwise.
 3. How can I find the angle between two lines if I only have their equations?
Ans. To find the angle between two lines if you only have their equations, you can first find the slopes of the lines using their coefficients. Then, substitute the slopes into the formula mentioned in the first question to calculate the angle.
 4. Is the angle between two lines affected by their position in the coordinate plane?
Ans. No, the angle between two lines is independent of their position in the coordinate plane. It solely depends on the slopes of the lines.
 5. Can the angle between two lines be greater than 90 degrees?
Ans. No, the angle between two lines will always be between 0 and 90 degrees. If the angle is greater than 90 degrees, it means the lines are not intersecting, and they are diverging from each other.
