Answer: Hyperbolic geometry
Step-by-step explanation:
Hyperbolic triangle is a non - Euclidean triangle in which the sum of the angles of the triangle is not up to 180 degrees. That is, less than 180 degree.
Euclidean geometry is the normal geometry that is being taught in school in which the sum of the angles of its triangle equals 180 degrees
While spherical geometry is a non euclidean geometry with sum of the angles of its triangle greater than 180 degrees.
Therefore, the triangle that has angle measures of 45°, 61°, and 70° is a non - Euclidean geometry which is hyperbolic geometry.
