(12) Line $l_{1}$ is parallel to line $l_{2}$, $l_{1}$ has 5 distinct points, and $l_{2}$ has 10 distinct points. Connecting the points on $l_{1}$ with the points on $l_{2}$ with line segments, if no three line segments intersect at the same point, then the number of intersection points between these line segments is $\qquad$ (answer with a specific number).
