How to Calculate Angle between two lines given direction ratios of two lines?
Angle between two lines given direction ratios of two lines calculator uses angle_b =
acos(((Direction ratio 1 of line1*Direction ratio 1 of line2)+(Direction ratio 2 of line1*Direction ratio 2 of line2)+(Direction ratio 3 of line1*Direction ratio 3 of line2))/(sqrt((Direction ratio 1 of line1)^2+(Direction ratio 2 of line1)^2+(Direction ratio 3 of line1)^2))*(sqrt((Direction ratio 1 of line2)^2+(Direction ratio 2 of line2)^2+(Direction ratio 3 of line2)^2))) to calculate the Angle B, Angle between two lines given direction ratios of two lines is defined as the angle formed by two lines corresponding to given direction ratios of two lines. Angle B and is denoted by ∠B symbol.
How to calculate Angle between two lines given direction ratios of two lines using this online calculator? To use this online calculator for Angle between two lines given direction ratios of two lines, enter Direction ratio 1 of line1 (a_{1_line1}), Direction ratio 1 of line2 (a_{1_line2}), Direction ratio 2 of line1 (b_{2_line1}), Direction ratio 2 of line2 (b_{2_line2}), Direction ratio 3 of line1 (c_{3_line1}) & Direction ratio 3 of line2 (c_{3_line2}) and hit the calculate button. Here is how the Angle between two lines given direction ratios of two lines calculation can be explained with given input values -> 69.71702 =
acos(((0.2*0.4)+(0.5*0.2)+(0.7*0.44))/(sqrt((0.2)^2+(0.5)^2+(0.7)^2))*(sqrt((0.4)^2+(0.2)^2+(0.44)^2))).
