How to Calculate Angle between two planes?
Angle between two planes calculator uses angle_c = acos(((Direction cosine 1 with respect to x axis*Direction cosine 2 with respect to x axis)+(Direction cosine 1 with respect to y axis*Direction cosine 2 with respect to y axis)+(Direction cosine 1 with respect to z axis*Direction cosine 2 with respect to z axis))/(sqrt((Direction cosine 1 with respect to x axis)^2+(Direction cosine 1 with respect to y axis)^2+(Direction cosine 1 with respect to z axis)^2)*
sqrt((Direction cosine 2 with respect to x axis)^2+(Direction cosine 2 with respect to y axis)^2+(Direction cosine 2 with respect to z axis)^2))) to calculate the Angle C, The Angle between two planes formula is defined as as the angle between the normal to them from any point. Angle C and is denoted by ∠C symbol.
How to calculate Angle between two planes using this online calculator? To use this online calculator for Angle between two planes, enter Direction cosine 1 with respect to x axis (l_{1}), Direction cosine 2 with respect to x axis (l_{2}), Direction cosine 1 with respect to y axis (m_{1}), Direction cosine 2 with respect to y axis (m_{2}), Direction cosine 1 with respect to z axis (n_{1}) & Direction cosine 2 with respect to z axis (n_{2}) and hit the calculate button. Here is how the Angle between two planes calculation can be explained with given input values -> 7.893159 = acos(((0.7*0.7)+(0.8*0.6)+(0.6*0.6))/(sqrt((0.7)^2+(0.8)^2+(0.6)^2)*
sqrt((0.7)^2+(0.6)^2+(0.6)^2))).
