|
|
|
|
|
|
|
|
DxAP = dBP × cos AAP , DyAP = dBP × sin AAP |

6. Dwukrotnie obliczamy współrzędne punktu P na podstawie: |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
a) współrzędnych punktu B i przyrostów boku BP: |
|
|
|
|
|
|
XP = XB + DxBP ; YP = YB + DyBP |

|
|
|
|
|
|
|
|
b) współrzędnych punktu A i przyrostów boku AP: |
|
|
|
|
|
|
XP = XA + DxAP ; YP = YA + DyAP |
