1 is correct!

through a point outside a given line, only one line can be drawn parallel to the given line

through a point outside a given line, only one line can be drawn parallel to the given line <=> Euclidean space

2 is wrong. Please try again.

through a point outside a given line, only one line can be drawn parallel to the given line

    { 1 } - Euclidean space
    { 2 } - elliptic space
    { 3 } - hyperbolic space

Riemannian space <=> elliptic space

3 is wrong. Please try again.

through a point outside a given line, only one line can be drawn parallel to the given line

    { 1 } - Euclidean space
    { 2 } - elliptic space
    { 3 } - hyperbolic space

the sum of the angles of a triangle is always less than 180 degrees <=> hyperbolic space
