There is a strong emphasis on the word included. Then the two triangles may not be similar if the equal angle is a non-included angle. Consider the following figure: Reference: https://www.math-only-math.com/images/side-angle-side-congruency.png Here in ∆KLM and ∆XYZ, KL = XY, ...

For instance, physics notes are always full of "equality" statements in which the expression on the RHS is just the definition of the quantity on the LHS. So why not use "equivalent to/ identical to/ equal to always, by definition"? [tex] K \equiv \frac{1}{2} mv^2 [/tex] [tex...
