The triangle construction - Paris Pamfilos We study the problem of constructing a triangle from the data {α, b-c, t_A}, t_A being the length of the internal angle bisector of angle A of a triangle with side lengths a, b, c, and angles α, β, γ. The key-point is the detection of a parabola intimately related to the construction problem. ✪ ✪ ✪ ✪ ✪ Link tải tài liệu: LINK TẢI TÀI LIỆU Theo LTTK Education
