Each angle in one triangle is congruent with (equal to) its corresponding angle in the other triangle i.e.: ∠A1 = ∠A2, ∠B1 = ∠B2 and ∠C1 = ∠C2. 2. The ratio of the length of one side of one triangle to the corresponding side in the other triangle is the same i.e.: tanₓ° (θ°) = opposite/adjacent of θ° in a x° triangle. Here we could define hypotenuse as the angle opposite to x°, opposite as the side opposite to θ° and adjacent as the side adjacent to θ° that is not the hypotenuse. And this should work because of triangle similarity (Euclid's Elements, Book VI, Proposition 4): angle 1 = x°.
