At what interior angle should Roberto continue his fence in order to meet Frederico's fence in a straight line? Why?
O 27º. The new angle is a consecutive interior angle of the original angle. Since the
original and final paths are parallel, the two angles must be supplementary
O 153. The new angle is an alternate interior angle of the original angle. Since the
original and final paths are parallel, the new angle must be congruent to the
original angle
O 270. The new angle is on a straight line with the original angle, so the two angles
must be supplementary
O 153º. The new angle is a corresponding angle of the original angle. Since the
original and final paths are parallel, the new angle must be congruent to the
original angle.
