Each exterior angle measures 120 degrees
equiangular triangle
Yes because the only way a triangle can be equiangular is if every angle is 60 degrees
Measure it. There is no formula for an exterior angle unless you have a regular (or equiangular) polygon. And there is no evidence to suggest that that is the case.
To write a two-column proof demonstrating that triangle EFB is equiangular given that triangle ABC is equiangular and line EF is parallel to AC, first list the given information in the left column. In the right column, write the corresponding statements: since EF is parallel to AC, by the Corresponding Angles Postulate, angle EFB is equal to angle ABC, and angle AEF is equal to angle CAB. Finally, since triangle ABC is equiangular, the third angle EBF will also be equal to angle ACB, proving triangle EFB is equiangular.
No there is not. A right triangle has to have an angle of 90 degrees. An equiangular triangle has 3 equal angles. If a right triangle was equiangular, it would be 90 times 3 equaling 270 degrees. There are only 180 degrees in a triangle.

No, it is impossible to draw an equiangular right triangle. An equiangular triangle has three 60o angles. A right triangle has one 90o angle, and two 45o angles.

It is: 180-interior angle = exterior angle
It is: 180-interior angle = exterior angle
60 degrees
60 degrees.
180 minus interior angle = exterior angle
