问题使我不得不制造两条三角,用点子来界定,然后检查它们是否类似。
我的第一部分是:正如女市长告诉我们的那样,创造了一个障碍点和一个障碍三角。 为了解决检查相似性的问题,我认为,我可以利用这些要点来界定病媒,他们利用宇宙法计算其视角,还有一些判决可以检查三角是否相似。
哪些法典可以帮助我实现这一目标? 我找不到我能够变成部分解决办法的任何东西。

What you said does the trick!
头三角地采取一些措施,如你所说:在任何垂直点和紧靠后方的长度方面,gle角(或焦炭——很容易用警棍计算)。
对另一个三角地来说,如果设想,看一角(或其胎体)是否相同,以及长度的比例是否相同。 你们必须用这种方式从所有3个vert子中进行这种检查(如果至少一个 fit,那么三 tri也一样)。
一种更快的方式是,总是从(针对国内)最小的角.开始,然后,你只需要作一次比较。
现在是:
You are given coordinates of all three points of each triangle. Let us consider two triangles T1 A(a1,a2) B(b1,b2) C(c1, c2), T2 P(p1,p2) Q(q1,q2) R(r1,r2).
So, for the two triangles to be similar, it has to follow the following conditions
1. AB = PQ; BC = QR; CA = RP
(We don t need their directions, So I am considering only magnitudes)
2. angle (A) = angle(B) i.e angle(BAC) = angle(QPR);
angle(B) = angle(Q) i.e angle(CBA) = angle (RQP) and
angle(C) = angle(R).
现在,你必须在这里协调地测量/地平地地测量。
COS (A) = ( b^2 + c^2 - a^2 )/2bc
COS (B) = ( c^2 + a^2 - b^2 )/2ac
COS (C) = (a^2 + b^2 - c^2)/2ab

(Similarly for P,Q,R of triangle T2).
Actually there is another rule by which its easy to do.
law: a/sin(A) = b/sin(B) = c/sin(C).
I think you have to go through Spherical Geometry
我希望这有助于你完成该方案。
How to do the program:
Actually, its fine if you want to use structures. Create a structure with fields of 3 sides and 3 angles. Thus you need to take two variables under structure type and compare those quantities mentioned above.
如果他们满意,他们也是类似的三角。
我希望这能帮助你。
