Answer:
CR=DS
Explanation:
We are given AB || PQ. CR and DS are perpendicular to line AB.
So, CR and DS are two perpendicular line between two parallel line.
As we know distance between two parallel line is constant at all point
CR is distance of two parallel line AB || PQ
DS is also distance of same parallel line AB||PQ
Therefore, CR must be equal to DS.
Thus, CR=DS is true statement.
