A triangle is equilateral if and only if it is equiangular.


**********************************************************


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ c^2\ =\ a^2\ +\ b^2]


where *[tex \Large c] is the measure of the hypotenuse and *[tex \Large a] and *[tex \Large b] are the measures of the legs.


Next time pay attention to the rules:  One question per post.
