4. Use the Euclidean Straightedge and Compass to draw each of the following: in all problems below a segment \( A B \) is given by its end points \( A \) and \( B \).: a. Construct segments \( 2,3,4 \), etc. times larger than \( A B \). b. A point \( C \) is known to lie outside the straight line \( A B \). Construct a point \( D \) symmetric to \( C \) with respect to \( A B \).
