Proofs concerning equilateral triangles About Transcript Sal proves that the angles of an equilateral triangle are all congruent (and therefore they all measure 60Â°), and conversely, that triangles with all congruent angles are equilateral.
Lung disorders or diseases in which a hyperresonant sound is heard upon percussion. small pneumothorax, lung hyperinflation due to emphysema or acute asthma attack.
