Saadiq constructed ∠ABC and an auxiliary line where he placed point D at one end. With the help of a compass and straightedge, what next step should Saadiq do to construct a copy of ∠ABC?

Answer 1

Saadiq should place the compass at point B and draw an arc that intersects both ray AB and ray BC. Then, he should place the compass at the point of intersection of the arcs and draw another arc inside the angle. Finally, he should use a straightedge to draw a line connecting point A to the point of intersection of the two arcs, forming a congruent copy of ∠ABC.
