Web31 aug. 2024 · 1 Since the area of a triangle is given by s i n ( A) b c 2, and there are two isosceles triangles which make up the rhombus (imagine drawing a diagonal, splitting the rhombus in two) we know that s i n ( A) b c = a r e a. (by applying the sine rule to each of the smaller triangles). WebTo find "a" solution, just choose one of the angles arbitrarily, so you know the position of three points (say A, B, C) in the plane. To find the fourth point D, you have to solve the equations: L 1 2 = ( C x − D x) 2 + ( C y − D y) 2. L 2 2 = ( B x − D x) 2 + ( B y − D y) 2. In the unknowns D x, D y.
