Solution

Using theorem, Sum of interior angles of a triangle is $180^{o}$
So, if a triangle has one angle $90^{o}$ , then sum of both other angles must be equal to $90^{o}$ .
Any angle cannot be equal to $0^{o}$ as it will not be a triangle in that case .
$∴$ A triangle cannot have more than one right angle.
