If one angle of a triangle is 90 degrees and one of the other angles is known, the third is thereby fixed, because the three angles of any triangle add up to 180 degrees. The two acute angles therefore add up to 90 degrees: they arecomplementary angles.The shape of a triangle is completely determined, except for similarity, by the angles.Once the angles are known, the ratios of the sides are

The big advantage of this approach is that graphene films formed at silicon carbide (SiC) surface can be directly used for sensor development since the substrate is a good insulator and the strong interaction between graphene and SiC creates a graphene bandgap to 0.26 eV, which is ideal for sensors whose detection is based in induced field effect .
