Even though RHS may seem like a special case of the SSA condition—typically unreliable for proving triangle congruence—this rule holds firm under specific circumstances. We dive deep into why RHS is valid, exploring the unique properties of right-angled triangles that make this rule work. Through a step-by-step proof, we demonstrate how the hypotenuse and one corresponding leg are enough to establish congruence, ensuring identical triangles every time.
