yes, when the ratio of the angles of a triangle is 1:2:3 then is it right to say that the greatest angle is 90 degrees.
EXPLANATION:-
Let's denote the smallest angle as X degrees. Then the other two angles are 2X and 3X.
X + 2X + 3X = 180
6X = 180
X = 30
It is a 30, 60, 90 triangle.

Ratio=1:2:3
Sum of the ratio=1+2+3=5
One angle-1÷5×90=15
Second angle-2÷5×90=30
Third angle-3÷5×90=45
Sum of the angle=90
15+30+45=90
90=90
Hence it is right to say that the greatest angle us 90
