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.

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion. Picture three angles of a triangle floating around. A. the angles formed by each pair of. adjacent sides on the inside of a polygon. B. each of the two nonadjacent interior. angles corresponding to each exterior. angle of a triangle. C. two angles whose measures have a sum. of 180 degrees. D. an angle formed by a side of a figure and. an extension of an adjacent side. Summary: The SAS criterion for triangle similarity states that if two sides of one triangle are proportional to two sides of another triangle and their included angles are congruent, then the triangles are similar. SSA which is not a way to prove that triangles are similar (just like it is not a way to prove that triangles are congruent).11 years ago. If you have two right triangles and the ratio of their hypotenuses is the same as the ratio of one of the sides, then the triangles are similar. (You know the missing side using the Pythagorean Theorem, and the missing side must also have the same ratio.) So I suppose that Sal left off the RHS similarity postulate.The figures are congruent because a 270° rotation about the origin and then a reflection over the x-axis will map ΔABC onto ΔLMN. 100% All answers correct!

Theorems include: a line parallel to one side of a triangle divides the other two proportionally, and conversely; the Pythagorean Theorem proved using triangle similarity. Using Triangle Similarity Theorems Right Triangle Similarity G-SRT.5. Firstly, if the triangles have 2+ matching corresponding angles, then it is similar. If it has side lengths that can be divided by a number, say X, and then match the side lengths of your other triangle, then it is similar. If it has 2 matching corresponding (see last sentence) sides, and the angle between these is the same, then it is similar.Definition: Triangles are similar if two sides in one triangle are in the same proportion to the corresponding sides in the other, and the included angle are equal.
