virtually one and the same, an equilateral triangle is an equal angle triangle. a triangle with 2 equal sides has 2 equal angles. a triangle with 3 unequal sides necessarily has 3 unequal angles.

(0, 1) to (8,4) has a side = sqr(9+49) = sqr58= about 7.6

(0,1) to (3,-7) has side = sqr(64+9) = sqr73= about 8.5

(8,4) to (3,-7) has side = sqr(25+121) = sqr146= about 12.1


off hand best guess is a scalene acute triangle all sides unequal, all angles unequal. all angles less than 90 degrees


not isosceles, not equilateral, not obtuse, not right triangle
