` = "Interface Angle"`
162.8935
The Interface Angle calculator computes the outer angle made by two intersecting right triangles defined by their pitch.
INSTRUCTIONS: Enter the following:
- (P1) Pitch 1
- (P2) Pitch 2
Interface Angle (B): The calculator returns the angle in degrees. However, this can be automatically converted to compatible units via the pull-down menu.
The Math / Science
The formula for the exterior angle of intersection of two right triangles is:
B = π + P1 - P2
where:
- B = Interface Angle
- P1 = Angle 1
- P2 = Angle 2
Note: P1 and P2 are two pitches. They are converted to radian angles.
