Question

1. what geometric construction is in progress in the image? copying an angle bisecting an angle constructing an interior arc bisecting a ray

Explanation:

The arcs drawn from the vertex B of angle ∠ABC are characteristic of the first - step in bisecting an angle. When bisecting an angle, we first draw an arc from the angle's vertex that intersects both rays of the angle. This is what is shown in the image.

Answer:

Bisecting an angle
