In hyperbolic geometry, a triangle could potentially have degrees.

In hyperbolic geometry, a triangle could potentially have less than 180 degrees.

Step-by-step explanation:

Hyperbolic geometry is the geometry, where we consider all postulates of Euclid except for the fifth one. We take the fifth postulate's negative form.

So, in this geometry, the angle sum of a triangle is less than 180°.
