lisov135 [29]
Explain how you can use a straightedge and a compass to construct and angle that is both congruent and adjacent to a given angle?

Answer: for this you will simply have to use the straightedge to draw two parallel lines and then you draw a line that goes through them that is perpendicular. You then use the compass to measure the angles, they should be congruent and adjacent.

I hope it helps, Regards.
