A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
An obtuse triangle can have no right angles, and has two equal angles.
A triangle has no right angles when it is not a right angle triangle as for example as in the case of an equilateral triangle that has 3 equal 60 degree angles.
a 'SCALENE' triangle. ; No equal sides, and no equal angles. An ISOSCELES triangle has two equal sides and two equal angles. An EQUILATERAL tringle has three equal sides and three equal angles all at 60 degrees. A RIGHT ANGLED triangle has one right angle (90 degrees) in it.
A triangle cannot have four angles.
A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
An obtuse triangle can have no right angles, and has two equal angles.
An EQUILATERAL Triangle. An ISOSCELES Triangle is two equal sides and two equal angles. A RIGHT-ANGLED Triangle has ONE right angle (90 degrees) A SCALENE Triangle has neither equal sides nor equal angles.
A triangle has no right angles when it is not a right angle triangle as for example as in the case of an equilateral triangle that has 3 equal 60 degree angles.

a triangle..
An isosceles triangle has two equal sides and two equal angles. A right triangle is any triangle with one angle that is a right angle. A right triangle could also be an isosceles triangle, but an isosceles triangle will not always have a right angle.
If one of the angles is 90 degrees then it is right ange triangle If one of the angles is obtuse then it is an obtuse triangle If the three angles are 3 different acute then it is a scalene triangle If two of the angles are equal then it is an isosceles triangle If the three angles are equal then it is an equilateral triangle
There can be no such triangle.
An isosceles triangle.
A right angled triangle can have two 45° angles if it is isoceles
