Can an obtuse triangle be regular why?
No - not a plane triangle. The angles of a regular triangle must be equal. So an obtuse triangle, if regular, would have three obtuse angles. The sum of the angles would then be greater than 3*90 = 270 degrees. But the sum of angles of a triangle must be 180 degrees.
What is a triangle with an obtuse angle?
