Formula of angle between two lines
WebSep 15, 2015 · There is a neat formula: tan α = m 1 − m 2 1 + m 1 m 2 Above is for acute angle between two straight lines. Where α is the angle between two straight lines and m 1 and m 2 are the slopes of those lines. Since we have a point B, we only need a slope to form an equation of the line that bisects the angle. WebApr 4, 2024 · Step 1: At first, We have to show that θ = θ₂ - θ₁ Step 2: For proving above, Let us consider ∆ABC By angle sum property we can state that θ + θ₂ + x = 180 …….. …

WebIf one of the line is parallel to y-axis then the angle between two straight lines is given by tan θ = ±1/m where ‘m’ is the slope of the other straight line. If the two lines are a 1 x + b 1 y + c 1 = 0 and a 2 x + b 2 y + c 2 = 0, then the formula becomes tan θ = (a 1 b 2 - b 1 a 2 )/ (a 1 a 2 + b 1 b 2 ) WebNotice the use of the absolute value to ensure that tan θ is equal to a positive number. Example 1 :- Find the angle between the following two lines. Line 1: 3x -2y = 4. line 2: x + 4y = 1. Solution :- Put 3x - 2y = 4 into slope-intercept form so you can clearly identify the slope. 3x - 2y = 4.
