Trèteaux Angles: R11m-DP
R11m-DP = Hip Rafter Miter Angle on Side Face Of Rotated Hip Rafter at Peak
Hip-Valley Roof Ratios Angle Formulas
- R11m-DP = arctan( (sin (90 - Jack Rafter Side Cut Angle ) ÷ tan ( C8 )) ÷ cos (90 - Jack Rafter Side Cut Angle ))
- R11m-DP = arctan( (sin (90 - P2m ) ÷ tan ( C8 )) ÷ cos (90 - P2m ))
The Trèteaux Angles Formulas for Hip Rafters Rotated into the Roof Surface Plane were developed by Sim Ayers and Joe Bartok.
