Question

1. which construction tool would be the best substitute for a straightedge?

compass
ruler
protractor
straightedge

Explanation:

A straightedge is used to draw straight lines. A ruler can also draw straight lines and has the added feature of measurement markings. A compass is for drawing circles, a protractor is for measuring angles, and choosing a straightedge as a substitute for itself is not logical.

Answer:

B. Ruler
