Are the triangles congruent?

You will write functions that measure the sides of a triangle given by its corners, compare two triangles, and build a triangle from two sides and the angle between them.

The idea. Two triangles with the same three side lengths are congruent (SSS). A triangle built from two sides and the angle between them (SAS) is fixed, so two such triangles with equal numbers are congruent.

Your tasks.

1. In side_lengths, return the three side lengths of the triangle, rounded to $6$ decimals and sorted from smallest to largest.
2. In congruent, return True when two triangles have the same sorted side lengths.
3. In sas_triangle, return the corners $A = (0, 0)$, $B = (s1, 0)$ and $C$ so that $AC = s2$ and the angle at $A$ is angle degrees.
4. Set same to the names in options whose triangle is congruent to sas_triangle(5, 4, 60).
