exists and is an alternate of . LL Congruence theorem says: If the two legs of one right triangle are congruent to the two legs of another right triangle, then the two right triangles are congruent.
The law of cosines generalizes the Pythagorean theorem, which holds only for right triangles: if the angle Î³ is a right angle (of measure 90Â°, or Ï2 radians), then cos Î³ = 0, and thus the law of cosines reduces to the Pythagorean theorem:
