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
