Answer 1

an obtuse triangle is a triangle with an angle that measures OVER 90 degrees, but less than 180 degrees. Therefore, each triangle with an angle that is in between 90 and 180 is an obtuse triangle because it has that one big angle :)

Answer 2

40 degrees, 40 degrees, 100 degrees
25 degrees, 60 degrees, 95 degrees
