In the figure below, is an equilateral triangle. How can we prove that ? There are multiple ways to prove this. , ; ; so you can use AAS, SAS (proving that must be congruent to ), or ASA (also proving that must be congruent to ) This proof is helpful in deriving the formulas for a 30°-60°-90° triangle. (see above)
