JohnWmAustin. 9 years ago. The Pythagorean Theorem is just a special case of another deeper theorem from Trigonometry called the Law of Cosines. c^2 = a^2 + b^2 -2*a*b*cos (C) where C is the angle opposite to the long side 'c'. When C = pi/2 (or 90 degrees if you insist) cos (90) = 0 and the term containing the cosine vanishes. Proving Base Angles of Isosceles Triangles Are Congruent. Given: is isosceles with AB ≅ BC .

Consider the two triangles. To prove that LMN ~ XYZ by the SSS similarity theorem using the information provided in the diagram, it would be enough additional information to know that. LM is 4 units and XZ is 6 units. In the diagram SQ/OM = SR/ON=4. To prove that the triangles are similar by the SSS similarity theorem, which other sides or ... Classified by sides, triangles can be equilateral, isosceles, or scalene. Triangles can also be classified using both their angles and sides. For example, an isosceles right triangle. The sides have a special relationship. The sum of the lengths of any two sides is greater than the length of the third side.
