Only if it has a right angle and 2 acute angles
No. The sum of all three angles must is 180 degrees. If there are 2 right angles (ie two angles of 90 degrees each), there is no scope for the third angle.
then the triangle is not a right trangle and has angles that are not 90 degrees.
A triangle that has all equal sides and angles.
The 3 interior angles of a triangle add up to 180 degrees

Yes, a triangle can have 2 congruent angles.
A scalene triangle.
A triangle that has all equal sides and angles.
180o
The 3 interior angles of a triangle add up to 180 degrees
Right Triangle
All three angles have different values. The sum of the three interior angles is 180 degrees.
Isosceles triangle.
A right triangle has one angle that is always 90degrees. The other angles vary from less than 90degrees to greater than 0degrees. The equilateral triangle always has all of its angles equal to 60degrees.
