is constructing a perpendicular bisector similar to constructing an angle bisector both constructions begin with a given angle

No, constructing a perpendicular bisector and constructing an angle bisector are different constructions.

Constructing a perpendicular bisector involves finding the line or segment that bisects another line segment at a right angle (90 degrees). This is done by finding the midpoint of the line segment and then constructing a line or segment perpendicular to it.

Constructing an angle bisector involves finding the line or segment that divides an angle into two equal parts. This is done by constructing an arc from each side of the angle, and then finding the point where the intersecting arcs meet. This point will be equidistant from each side of the angle and will bisect the angle.

No, constructing a perpendicular bisector is not similar to constructing an angle bisector, even though both constructions might begin with a given angle.

Constructing a perpendicular bisector involves finding a line or segment that divides another line or segment into two equal parts and is perpendicular to that line or segment. This process requires constructing a circle with the given line or segment as the diameter and finding the midpoint, which then acts as the perpendicular bisector.

On the other hand, constructing an angle bisector involves finding a line or ray that divides an angle into two equal parts. This process requires constructing two arcs with the same radius from the arms of the angle, and then drawing a line connecting the intersections of the arcs with the angle. This line is the angle bisector.

While both constructions may begin with a given angle, the methods and steps involved in constructing a perpendicular bisector and an angle bisector are different.
