My English is very bad, please forgive me. I have the triangle(is not Right triangle). I knew the all length and all vertices' position of the triangle, cross plane(white)(1*1cm) and the pivot point of cross plane(white) is object center. I want to move and scale the cross plane(white) to fit the right and top vertex of triangle like image. How to find the distance and proportion to become bigger cross plane(green)? Many thanks.
PS. pivot point like image
